Starts scrolling when dragging a node or node link and going outside the current window.
Largely copied from the VIEW2D_OT_edge_pan operator.
Edge panning operator customdata and supporting functions now in
UI_view2d.h, so they could be used by operators in other editor
libraries. The VIEW2D_OT_edge_pan operator also uses this customdata and
shared functions now. Operators properties can be used to configure
edge panning margins and speed for each use case, rather than using
hardcoded values.
The speed function for edge panning has been tweaked somewhat:
* "Speed per pixel" has been replaced with a "speed ramp" distance.
This is more intuitive and also creates an upper bound for the speed,
which can otherwise become extreme with large cursor distance.
* "Max speed" is reached at the end of the speed ramp.
* Padding the region inside and outside is applied as before, but both
values are operator properties now.
Node transform operator also supports edge panning. This requires
an offset for changes in the view2d rect, otherwise nodes are "stuck"
to the original view.
Transform operator had cursor wrapping categorically enabled, but this
gets quite confusing with the edge scrolling mechanism. A new TransInfo
option T_NO_CURSOR_WRAP has been introduced to disable this behavior.
The double negative is a bit annoying, but want to avoid affecting the
existing transform modes, so by default it should still set the
OP_IS_MODAL_GRAB_CURSOR flag (which then sets the WM_CURSOR_WRAP_XY
flag during modal execution).

- Zooming out a lot faster than zooming in,
it had the wrong aspect ratio, make all the preparations
with the factors instead of deltas.
- Improved following the `zoom_invert`
(should not apply to `MOUSEZOOM`) and "trackpad natural scroll"
preferences.
- `zoomfac` adjustment, same as in `view_zoomdrag_modal`.

When using a trackpad Zoom to Mouse Position would always zoom to center of canvas.

Actually, fixes compile error and an incorrect poll.
Caused by 21fc4ae206 and 3a1cf838ca.
The poll has to perfrom the `view_zoom_poll()` logic to ensure correct context.
Multiple related issues:
* `view_zoomdrag_exec()` required `view_zoomdrag_init()` to be called first to
set up data. Can now easily be done in the `_exec()` function as well though.
* Because of that the operators could not be called in an `EXEC_` context (e.g.
`EXEC_REGION_WIN`).
* With "Zoom to Mouse Position" enabled, zooming from a menu or script would
zoom to the mouse position. That should only happen if the operators are
called directly in the editor.
`view_zoomdrag_init()` would perform a number of sanity checks that
`view_zoom_poll()` already executed. The design of operators forsees that
(non-expensive) context sanity checks are done by the `poll()` callbacks, and
the execution callbacks can then just assume that happened. No reason to be
overly pedantic, we don't do that elsewhere either.
Note that this code is from the earliest days of an operator design. So it's
not surprising that it wasn't using the design "properly".
Use 'dpi_fac' instead of 'pixelsize' to scale input sensitivity
based on the interface scale.
Also use dpi_fac for view zoom operator.
Thanks to @ISS for investigating.
The abbreviation 'init' is brief, unambiguous and already used
in thousands of places, also initialize is often accidentally
written with British spelling.
Currently if you drag and drop an item from the outliner elsewhere in
the Blender window, the outliner will scroll the entire time, even if the
mouse is far away. This commit adds optional behavior for the edge pan
operator that makes it only act if the mouse is close enough to the region.

This addresses warnings from Clang-Tidy's `readability-else-after-return`

No functional changes.
View2DScrollers used the memory manager to allocate memory. This isn't a
problem but in a upcoming change the scrollers will be drawn more often
than it used to (See {D8066}). To limit the number of allocations and
frees this patch will use the stack for allocation.

This adds a modal operator called Edge Pan, which is meant to run invisibly
while something inside a region is being dragged. This patch applies this
to dragging panels, but it can be used elsewhere too.
The speed (which is defined relative to how far the mouse is beyond the
boundary) and delay are easily adjustible. and the speed also increases
smoothly from a start value to a max to make it feel more interactive
and less robotic.

Follow up of b2ee1770d4 and 10c2254d41, part of T74432.
Now the area and region naming conventions should be less confusing.
Mostly a careful batch rename but had to do few smaller fixes.
Also ran clang-format on affected files.
Both the MS headers and blender headers define the HKEY
which gives all kind of inclusion order issues.
This diff renames all *KEY constants to EVT_*KEY to resolve
this conflict.

There's a chance that this causes some issues becaue in some cases we
change from getting the window from context to getting it from somewhere
else.
There was a mix of old and new constants. Now have one list of WM_CURSOR_*
cursor types, using GHOST standard cursors when available and otherwise falling
back to our custom cursors.
