Fix T81951: Add Cube new tool surface snaping not working

For the `plane_depth` of type `PLACE_DEPTH_SURFACE` to take effect, a `snap_context` is needed.

But, even if a temporary `snap_context` was created for `plane_orient == PLACE_ORIENT_SURFACE`,
this context was not used for `plane_depth`.

So, use a temporary `snap_context` for `PLACE_DEPTH_SURFACE` (as it is done for `PLACE_ORIENT_SURFACE`).

LibOverride: Optimize deletion of overrides in liboverride delete.

Fix T82561: shader compilation crashes in OSL

The "type" sockets on shader nodes were renamed in rB31a620b9420cab to
avoid clashes with the `NodeType type` member from the Node base class,
but the OSL shader compilation was missing those changes.

cleanup, merge loops on shaders for detecting changes

fix infinite recursion

do instancing with dupli system

Cleanup: const, renames, remove single use variables.

Animation: Expand unit tests for `BKE_fcurve_active_keyframe_index()`

Expand unit test for `BKE_fcurve_active_keyframe_index()` to test edge
cases better.

This also introduces a new test macro `EXPECT_BLI_ASSERT()`, which can be
used to test that an assertion fails successfully.

No functional changes to actual Blender code.

Multires: Cleanup, clarify comment

Cleanup/Update comments in liboverride code.

consolidate flags into a single enumeration

Fix own previous commit re testing of `BLI_rel_path`.

Windows would need its own version of those tests, for now just
disabling them on that platform.

install_deps: fix a typo in argument handling of new nanovdb option.

Spotted by Patrick Mours (@pmoursnv), thanks!

Merge remote-tracking branch 'origin/blender-v2.91-release'

Animation: More explicit boundary checks when setting active keyframe

Fix unit test failing in debug mode by having more explicit boundary checks
when setting an FCurve's active keyframe.

No functional changes.
