This adds support for showing geometry passed to the Viewer in the 3d
viewport (instead of just in the spreadsheet). The "viewer geometry"
bypasses the group output. So it is not necessary to change the final
output of the node group to be able to see the intermediate geometry.
**Activation and deactivation of a viewer node**
* A viewer node is activated by clicking on it.
* Ctrl+shift+click on any node/socket connects it to the viewer and
makes it active.
* Ctrl+shift+click in empty space deactivates the active viewer.
* When the active viewer is not visible anymore (e.g. another object
is selected, or the current node group is exit), it is deactivated.
* Clicking on the icon in the header of the Viewer node toggles whether
its active or not.
**Pinning**
* The spreadsheet still allows pinning the active viewer as before.
When pinned, the spreadsheet still references the viewer node even
when it becomes inactive.
* The viewport does not support pinning at the moment. It always shows
the active viewer.
**Attribute**
* When a field is linked to the second input of the viewer node it is
displayed as an overlay in the viewport.
* When possible the correct domain for the attribute is determined
automatically. This does not work in all cases. It falls back to the
face corner domain on meshes and the point domain on curves. When
necessary, the domain can be picked manually.
* The spreadsheet now only shows the "Viewer" column for the domain
that is selected in the Viewer node.
* Instance attributes are visualized as a constant color per instance.
**Viewport Options**
* The attribute overlay opacity can be controlled with the "Viewer Node"
setting in the overlays popover.
* A viewport can be configured not to show intermediate viewer-geometry
by disabling the "Viewer Node" option in the "View" menu.
**Implementation Details**
* The "spreadsheet context path" was generalized to a "viewer path" that
is used in more places now.
* The viewer node itself determines the attribute domain, evaluates the
field and stores the result in a `.viewer` attribute.
* A new "viewer attribute' overlay displays the data from the `.viewer`
attribute.
* The ground truth for the active viewer node is stored in the workspace
now. Node editors, spreadsheets and viewports retrieve the active
viewer from there unless they are pinned.
* The depsgraph object iterator has a new "viewer path" setting. When set,
the viewed geometry of the corresponding object is part of the iterator
instead of the final evaluated geometry.
* To support the instance attribute overlay `DupliObject` was extended
to contain the information necessary for drawing the overlay.
* The ctrl+shift+click operator has been refactored so that it can make
existing links to viewers active again.
* The auto-domain-detection in the Viewer node works by checking the
"preferred domain" for every field input. If there is not exactly one
preferred domain, the fallback is used.
Known limitations:
* Loose edges of meshes don't have the attribute overlay. This could be
added separately if necessary.
* Some attributes are hard to visualize as a color directly. For example,
the values might have to be normalized or some should be drawn as arrays.
For now, we encourage users to build node groups that generate appropriate
viewer-geometry. We might include some of that functionality in future versions.
Support for displaying attribute values as text in the viewport is planned as well.
* There seems to be an issue with the attribute overlay for pointclouds on
nvidia gpus, to be investigated.

This is required by the Metal backend to perform flushing of temporary objective-C resources. This is implemented as a global autoreleasepool, and is to ensure consistency such that all rendering operations, whether called via events, or via main loop will be within an autoreleasepool.

Handling the OS key now match other modifiers in GHOST which detect
each key separately, making the behavior simpler to reason about since
mapping a single key to a modifier state is simpler, avoiding handling
that only applied to the OS-Key.
This means simulating key up/down events can use the correct modifier.
In the window-manager this is still only accessed accessed via KM_OSKEY.
Related to {D15885} that requires scene parameter
to be added in many places. To speed up the review process
the adding of the scene parameter was added in a separate
patch.

While missing the break before a default that only breaks isn't
an error, it means adding new cases needs to remember to add the
break for an existing case, changing the default case will also
result in an unintended fall-through.
Also avoid `default:;` and add an explicit break.
Since [0] notifiers were cleared and left in the queue, while harmless
it meant the call to remove the notifier from the set was redundant.
Now set aside a category to tag notifiers as having been cleared and
skip them entirely.

Pressing escape when rendering a viewport animation would
access the freed even and crash (with ASAN enabled).
Always check the context's window before the event as this is a signal
a file was loaded or the window was closed (and it's events freed).
Always use modifier keys from the active window, as changes to the
modifiers aren't sent to inactive windows.
Also resolves modifier keys being lost on window de-activation.
Activating the window again would check the previous state of the
modifiers which was always cleared as of [0],
now clearing is no longer needed.

The ISMOUSE macro was used in situations only button events
needed to be checked.
The only functional difference would be MOUSEMOVE events were
previously accepted for these checks.
The goal of this change is to fix an increasing bottleneck of the event
queue handling when there is an operator bound to a key press event and
is taking longer to finish than a key-repeat speed on the system.
Practical example of when it happens is the marker tracking operator in
a single-frame track mode. Quite often artists will hold down Alt-arrow
to track a segment of footage which seems trivial to track. The issue
arises when the Alt-arrow is released: prior to this change it is was
possible that more frames will be tracked. It also seems that redraws
are less smooth.
It is a bit hard to make easily shareable computer-independent test
case. Instead, a synthetic case can be reproduced by adding a 50 ms
sleep in the `text_move_exec()`. In such synthetic case open a long
text in the text editor and hold left/right arrow button to navigate
the cursor. The observed behavior is that seemingly redraws happen
less and less often and cursor travels longer and longer distances
between redraws. The cursor will also keep moving after the buttons
has been released.
The proposed solution is to ignore sequential key-press events from
being added to the event queue. This seems to be the least intrusive
and the most safe approach:
- If the operator is fast enough there will be no multiple press events
in the queue in both prior and after of this change.
- If the operator is slow enough, clicking the button multiple times
(i.e. clicking arrow button 3 times in a heavy shot will change the
scene frame by exactly 3 frames because no events are ignored in
this case).
- Only do it for key press events, keeping mouse and tabled behavior
unchanged which is crucial for the paint mode.
Note that this is a bit different from the key repeat tracking and
filtering which is already implemented for keymaps as here we only want
to avoid the event queue build-up and do want to ignore all repeat
events. In other words: we do want to handle as many key presses as the
operator performance allows it without clogging anything.
A possible extension to this change could be a key press counter, so
that instead of ignoring the event we merge it into the last event in
the queue, incrementing some counter. This way if some operator really
needs to know exact number of key repeats it can still access it.

- Remove references to `ISTEXTINPUT` as any keyboard event with it's
utf8_buf set can be handled as text input.
- Update references to the key repeat flag.
The `ascii` member was only kept for historic reason as some platforms
didn't support utf8 when it was first introduced.
Remove the `ascii` struct members since many checks used this as a
fall-back for utf8_buf not being set which isn't needed.
There are a few cases where it's convenient to access the ASCII value
of an event (or nil) so a function has been added to do that.
*Details*
- WM_event_utf8_to_ascii() has been added for the few cases an events
ASCII value needs to be accessed, this just avoids having to do
multi-byte character checks in-line.
- RNA Event.ascii remains, using utf8_buf[0] for single byte characters.
- GHOST_TEventKeyData.ascii has been removed.
- To avoid regressions non-ASCII Latin1 characters from GHOST are
converted into multi-byte UTF8, when building X11 without
XInput & X_HAVE_UTF8_STRING it seems like could still occur.
Regression in [0] caused operations such as file-load or file-new
from any window besides the first to write into the freed:
`wmWindow.eventstate`.
Resolve by copying the event instead of restoring the region relative
cursor position after modifying it.

Fix by always testing unhandled double-click events as press events,
irrespective of the previous event type.
**Details**
Handling double-click events only ran when the previously pressed-key
matched the current pressed-key.
Originally when double-click support was added the previous type was
compared (ignoring it's press/release value) and while not necessary
it was harmless as it matched the check for double-click events being
generated.
As of [0] the logic for click/drag detection changed to ignore release
events as release this could interrupt dragging.
This made it possible to generate double-click events that failed the
`event->prev_press_type == event->type` comparison.
In these cases it was possible to generate double-click
events that would not fall-back to a 'press' value when unhandled.

- Avoid ambiguity which caused these values to be confused, use `mval`
for region relative mouse coordinates, otherwise `event_xy`.
- Pass region relative coordinates to sample_detail_dyntopo &
sample_detail_voxel as there is no reason to use screen-space values.
- Rename invalid use of mval for screen-space coordinates.
Wayland doesn't support accessing the position making functionality that
would map events to other windows fail, sometimes considering windows
overlapping when they weren't (as all window positions were zeroed).
Disable dragging between windows when accessing the window the position
