UI: add UILayout.direction

Read only attribute, needed for introspection.

UI: add method to draw menu contents

This supports expanding menu contents into an existing layout.

Needed to fix T58937.

Fix possible key collision w/ BKE_id_to_unique_string_key

BKE_id_full_name_get doesn't ensure unique output, use a simple
method to create a unique key, guaranteed not to collide.

Fix T59626: Outliner rename overlaps icons

Fix for T59219 was using low alpha-light grey for text background
so editing text would always be slightly brighter then the existing
background.

This causes outliner rename to have low alpha making text overlap
icons.

Use solid color to avoid issues with overlapping UI
elements in the future.

Fix T59579: Grease Pencil copy buffer loses material information

Mesh Batch Cache: Fix uninitialized loop variable

Fix crash clicking on trackball widget

Missing check in newly added gizmo orientations.

Cleanup: argument wrapping indentation

UI: expose gizmo orientation as a single enum

Avoids awkward logic from the popover,
by faking an extra item in the enum.

Fix T59391: Crash snapping to active

Fix T59387: Axis target crash

GP: Fix error drawing on Camera view for Surface/Stroke

This bug was introduced fixing task T59595

GP: Primitive: Add MMB to confirm

Based on GP team feedback

Fix T59595: Grease Pencil and CameraView

The perspective effect deformed the stroke. Now when you are in camera view and the lock axis is not enabled, the stroke is reprojected flat over the view to remove any deformation.

Also fixed reproject operator to use the origin set in topbar and not cursor 3D always.

Fix T59574: Prop_search fails to set objects from scene.

Another case where editstr from search button would be used, when we
actually have desired pointer itself already available in button.

Am growing tired of doing bandaids fixes on that search menu stuff,
whole thing would require some real re-coding imho, to get rid of that
tantacular dependency over string 'identifier' only (when we should also
have access to at the very least, the active index, and also probably
active data pointer itself...).
And/or clearly separate string identifier from 'UI' string shown to user.

Fix T58376: incorrect tooltip in subsurf modifier

Fix (unreported): Wireframe fails in the sculpt mode on some AMD GPUs.

Fix T59273: Text object disappears when Fill Mode is set to None

Fixes for particle system and physics

- Silence harmless error print about relation.

Object with particle system which doesn't use physics will
not have point cache component.

- Tag relations for update when particle system physics type
change.

This ensures correct state of point cache component.

This is all part of T59258.

Fix T58739: Camera Location, keyframe Bug

This was originally caused by fix for T53788. Not sure why extra
`where_is` is needed there, the object is supposed to be evaluated
already.
