Build: use non-interactive svn commands for "make update"

Needed for buildbot, but interactively solving svn conflicts in the middle
of manual make update is also not ideal.

Rename internal VAMR files (mainly removes VAMR_ prefix)

Also rename VAMR_internal.h to utils.h and move OpenXR include out of
it.

Use VAMR namespace for internal types

Drivers: support explicit euler rotation order for transform channels.

The meaning of the euler angles completely depends on the rotation
order. Currently the rotation order is taken from the target of the
driver variable, which somewhat makes sense if it uses euler, but if
it's quaternion, then the order is always set to XYZ.

Add a new option for the rotation channels of the Transform Channel
driver variables that defaults to the old behavior, but allows setting
an explicit rotation order.

Remove unnecessary WITH_OPENXR definition in BKE

Remove Ghost-XR code

Also fixes remaining call to it.

Call VAMR functions in window-manager, not GHOST_Xr

This gives linking errors currently because of conflicting symbols, but
that is to be expected and will be fixed in a followup.

Add missing C-API source file

Also add missing license header.

Cleanup: rename natural string comparison

Merge branch 'master' into greasepencil-object

Outliner: fix unnecessary syncing

Depending on the outliner display mode and the outliner dirty state,
a sync may not be needed on each draw. This commit adds a check
before syncing to prevent syncing when not needed.

Outliner: always sync object selection

This changes from-outliner selection syncing to always sync the
selection state of objects. This allows selecting objects while in
edit mode for parenting or adding hooks. This also fixes a few issues
where the sync algorithm would fail when no active object existed.

Cleanup: clang-format

MSVC: Fix BlendThumb debug build.

Spotted by @deadpin on chat

GPencil: Fix move_to_layer menu in Stroke context menu

Missing in previous commit

make_deps: remove blendthumb

now in regular codebase.

Transform: use recalc geometry depsgraph tag

Better be specific with the data that needs updating.

Fix T69299: Transform origin & skip-children jitters

Cleanup: 2 space indentation

Windows: Fix compatibility with older cmake

Older cmake did not find the BlendThumb sub project.
