Out of bounds read and potential out-of-bounds write when transforming

While this didn't cause user visible bugs in my tests,

Adds navigation transforms (pose, scale) to the XR session state that
will be applied to the viewer/controller poses. By manipulating these
values, a viewer can move through the VR viewport without the need to
physically walk through it.
Add-ons can access these transforms via Python
(XrSessionState.navigation_location/rotation/scale) to use with custom
operators.
Also adds 3 new VR navigation operators that will be exposed to users
as default actions in the VR Scene Inspection add-on. While all three
of these operators have custom properties that can greatly influence
their behaviors, for now these properties will not be accessible by
users from the UI. However, other add-ons can still set these custom
properties if they desire.
1). Raycast-based teleport
Moves the user to a location pointed at on a mesh object. The result
can optionally be constrained to specific axes, for example to achieve
"elevation snapping" behavior by constraining to the Z-axis. In
addition, one can specify an interpolation factor and offset.
Credit to KISKA for the elevation snapping concept.
2). "Grab" navigation
Moves the user through the viewport by pressing inputs on one or two
held controllers and applying deltas to the navigation matrix based on
the displacement of these controllers. When inputs on both controllers
are pressed at the same time (bimanual interaction), the user can scale
themselves relative to the scene based on the distance between the
controllers.
Also supports locks for location, rotation, and scale.
3). Fly navigation
Navigates the viewport by pressing a button and moving/turning relative to
navigation space or the VR viewer or controller. Via the operator's
properties, one can select from a variety of these modes as well as
specify the min/max speed and whether to lock elevation.

This was caused by strips with single frame input like single image
strip or color strip. their length is always 1, and so content length
was calculated to end after first frame.
There was code handling this case, but it was also checking for
`anim_endofs` and `endstill` values. Anim offset values have no effect
on these strips and still frame value was used incorrectly. So these
chacks can be removed completely.
This was caused by snap to hold offset feature, which calculates strip
content boundary, but it can be outside of strip boundary.
Clamp content start and end values so they are always inside of strip.
This change simplifies the parameter list for these functions
and reduces the chance of typos mixing up array indices.

Use arrays for wmEvent coordinates, this quiets warnings with GCC11.
- `x, y` -> `xy`.
- `prevx, prevy` -> `prev_xy`.
- `prevclickx, prevclicky` -> `prev_click_xy`.
There is still some cleanup such as using `copy_v2_v2_int()`,
this can be done separately.

Adds a button, Update All Paths, to the Motion Paths property tabs and
will always show. The operator goes through all visible objects and
updates their motion paths.
The current implementation has a subtle functional change. Calculating
or updating motion paths for armature objects (through the Object tab,
not Armature tab) now also updates the paths for its bones. We could
preserve the old behavior but it doesn't seem necessary. It seems more
likely that the animator wants to update both anyways.

Regression introduced in {rBb0d9e6797fb8}.
Previously the Graphics Editor had a conflict with two different snap
types. Auto-Snap and Snap with Ctrl.
It is now clearer which snap should prevail.
Strip was flagged for deletion in `seq_transform_handle_overwrite()`
on `STRIP_OVERLAP_IS_FULL`. Then it is removed in
`SEQ_edit_strip_split()` before it should be.
Handle `STRIP_OVERLAP_IS_FULL` in separate loop.
This may not be complete solution, because in example file overlap is
caused between 2 transformed strips and one that is "static".
Such operation should not be possible in first place. This fixes the
crash at lest, so improvement in behavior can be handled separately.

Make the "xform" tool/gizmo available for strip transformations in the
sequencer preview window.
Because of the amount of hacks needed to make the gizmo work nicely with
multiple strips at the same time, it was decided to only show the
translate gizmo when multiple strips are selected.
This is because the transforms with multiple strips would appear buggy
because of our lack of shearing support in the transform system.
There is also currently no way to properly sync the gizmo drawing with
the transform when using multiple strips.

- Use 2D cursor in the preview space using shortcuts

- Add Cursor tool, cursor transform.
- Support for cursor and bound-box pivot.
- Add pivot pie menu.
`SequencesMeta.new_movie()` API function caused meta strip to change
length. Similar issue has been fixed in transform code by checking
if `MetaStack` exists. `MetaStack` is not used when changing data in
python.
Provide `seqbase` to `SEQ_time_update_sequence()` so the function can
check if change happens inside of meta strip.
This patch also merges `seq_time_update_sequence_bounds()` into
`SEQ_time_update_sequence()`. This is because same issue applies for
both functions and it is confusing to have more time update
functions.re if this will lead anywhere.

This ended up being a copy of:
`toolsettings->workspace_tool_type == SCE_WORKSPACE_TOOL_FALLBACK`
requiring boiler plate assignment in gizmos refresh callbacks.
Remove this struct member and check `toolsettings->workspace_tool_type`
directly, since so far there has been no advantage in gizmo-groups
being able to control this themselves.
`BKE_mesh_boundbox_get` cannot be called for objects of type Curve.
The BoundBox however does not match the object seen in the scene.

Implements T89789, T89792, custom grid (described as dynamic grid in
T78389) and UV grid snapping (T78391)
Replaces the default UV editor grid with 2 new types of grid :
* Custom grid: Allows the user to create an NxN grid, where the value
of N is specified by the user.
* Subdividing grid: Subdivides the UV editor grid when the user
zooms in the viewport and vice versa when zooming out.
UV snapping improvements :
* Increment snapping: Increment values for snapping are calculated based
on which grid type is being used in the UV editor
(subdividing or custom). In general the increment value is equal to
the distance between 2 visible grid lines.
* Absolute grid snap: New toggle added to increment snapping option in
the UV editor, allows UV grid snapping during translation.

NLA and Dope Sheet use a specific transform operation to scale.
Unlike the conventional resize operation, `TIME_SCALE` operates on `td->val`.
This is a bit outside the convention of transform operators.
The expected thing in this case would be to work in `td->loc` and use the conventional resize operator.
But for now, to fix the problem, use `td->loc` in the `TIME_SCALE` operation.
This commit also brings a cleanup in the style of some comments and removing unnecessary `memset`.
