Fix T82607: crash cancelling Cycles render during adaptive subdivision update

Now that the Blender sync mechanism deletes nodes from the scene, we need to
ensure scene update is stopped before we do this.

Also add some more early out in scene geometry update to ensure we do not
continue working on incomplete geometry data, though that was not the cause of
this crash.

Cleanup: remove accidentally committed merge files

Cleanup: compiler warning

Fix T82516: Cycles crash updateding animated volumes after NanoVDB

Two issues:
* Automatic deduplication of OpenVDB grid data was failing when Cycles had
already cleared the OpenVDB grid, causing an empty grid. Instead rely on
Blender return the same OpenVDB grid pointer when deduplication is possible.
* The volume bounds mesh was not properly cleared when the OpenVDB grid was
empty, causing a mismatch between mesh and voxel data.

fix: added missing float declarations

Test cases for vec_roll_to_mat3_normalized

The function vec_roll_to_mat3_normalized() basically has to handle 3 scenarios:

- When a bone is oriented along the negative Y axis
- When a bone is very close to the negative Y axis
- All other cases

The tests in the Differential make sure that all 3 situations are covered.

Fix empty Cycles render devices panel showing in preferences on macOS

There is no GPU rendering support on macOS, so showing the panel only adds
confusion. Also hide the panels in builds without Cycles.

Fix asserts when two (or more) SplineIK constraints have the same root

Only a single DEG operation node `POSE_SPLINE_IK_SOLVER` should
be added in this case [ see `build_splineik_pose`, same is already done

Fluid: Removed clamp from force assignment

The clamp is too aggressive and results in forces being too weak.

Fix NanoVDB not being enabled/disabled correctly in CMake profiles

This caused warnings when e.g. building the lite profile because NanoVDB was not disabled, but
OpenVDB was. This Fixes this by setting the "WITH_NANOVDB" flag too.

Fix T81813: Keyframe handles don't follow keyframes

Add a new property `co_ui` to Keyframes, the modification of which will
apply to the keyframe itself as well as its B�zier handles.

Dragging the "Keyframe" slider in the properties panel now maintains the
deltas between the keyframe and its handles, just like moving the key in
the graph editor would.

Codesign: Report codesign errors from server to worker

Pass codesign errors (if any) from codesign buildbot server to the
buildbot worker, so that the latter one can abort build process if
the error happens. This solves issues when non-properly-notarized
DMG package gets uploaded to the buildbot website.
