Moved USD importer files to import directory.

Fix T81467: Crash with KD-Tree Weld Modifier

The problem is related to the `use_index_order` option of `BLI_kdtree_3d_calc_duplicates_fast`.
With this option, the higher index is expected to be less than `tree->nodes_len`.

Fix T81589: Correct drag type handling in outliner

Blender crashed when dragging and dropping color into the outliner.
This issue was cause by a missing check for the correct drag type
in `datastack_drop_poll`. The check is added in this commit.
Additionally, a new drag type is introduced for the "data stack"
drag option, that was introduced in commit 1572da858df4, to
differentiate it from the existing WM_DRAG_ID type.

Cleanup: Rename outliner helper function

This name makes more sense and is consistent with related functions
(e.g. `outliner_requires_rebuild_on_select_or_active_change()`).

Fix T81555: Outliner object state filter not updating correctly

When changing the selected, active or visible object(s), the Outliner
has to be rebuilt while using the corresponding object state filters.

The object hiding operators also have to send the proper notifiers (they
changed visibility without notifying about that).

Animation: fix assertion failure on unsetting active keyframe

Avoid NULL pointer dereference when checking keyframe selection state in
`BLI_assert()` call.

Cleanup: split `animchan_sync_fcurve()` into smaller functions

Split `animchan_sync_fcurve()` into functions for handling Scenes and
Node Trees.

No functional changes.

Animation: enforce that the active keyframe is always selected

Check selection state in `BKE_fcurve_active_keyframe_index()`, and only
return the active keyframe index when that keyframe is actually selected.
This is now also asserted in the `BKE_fcurve_active_keyframe_set()` function,
which is now also used when inserting a keyframe.

Fix T81551: Cycles crash updating volume with modifiers

The volume bounds mesh was being rebuilt too often, it should only be done
when rebuilding the BVH as well, otherwise they can go out of sync.

File Browser/macOS: Don't treat .app as directory

While there are other bundles which show up as directories,
`.app` are the most common ones.

*Users should not be saving anything inside .app bundles, nor using
Blender to edit any of the files.
*This declutters the File Browser for say ~/Applications folder
or recursive search on a path with apps.
*Matches Finder's behavior of showing apps as files. (We don't have a
"right click > show package contents" button like Finder though)

This change shows `.app` files like incompatible files, or `.exe`s
on Windows.
