Fix T71412: Add transform component to deforming modifier

Dynamically bound mesh deform modifiers failed to update the viewport on
object transformation of deformer. The TODO by Sergey, which suggested
adding the transform component to the depsgraph, was already there, and
worked to fix T71412.

Fix T71621: VSE crashes when playing last frame of audio

Due to some floating point errors the last frame of a VSE audio strip can
cause integer overflow and crash Blender. This overflow was caused by a
cast from `int64_t` to `int` without prior check. The crash is fixed by
keeping the variable as `int64_t` for as long as possible.

Bevel: Custom Profile and CurveProfile Widget

Custom profiles in bevel allows the profile curve to be controlled by
manually placed control points. Orientation is regularized along
groups of edges, and the 'pipe case' is updated. This commit includes
many updates to comments and changed variable names as well.

A 'cutoff' vertex mesh method is added to bevel in addition to the
existing grid fill option for replacing vertices.

The UI of the bevel modifier and tool are updated and unified.

Also, a 'CurveProfile' widget is added to BKE for defining the profile
in the interface, which may be useful in other situations.

Many thanks to Howard, my mentor for this GSoC project.

Alembic: clean up exporter metadata code

The Alembic file metadata object was created in one place, a bit of
metadata was added, then it was passed along with other properties which
were then injected as metadata in another function. This is now cleaned up.

No functional changes.

Alembic: Upgrade from 1.7.8 to 1.7.12

Alembic 1.7.12 introduces a 'DCC FPS' hint, allowing Blender to write
the scene frame rate to the Alembic file. This will make it possible for
importers and converters to properly deal with situations where 'frame
number' is the only reference to time.

Writing this new DCC FPS hint will be done in a separate commit. Here
only the Alembic library is upgraded from 1.7.8 to 1.7.12.

Cleanup: remove WITH_RAYOPTIMIZATION

This is redundant as WITH_CPU_SSE adds these flags

Outliner: Fixup for previous commit on tooltip/crash fix

The issue was actually in Python extras (where it shows the ENUM option).

I got a bit distracted by the "(undocumented operator)" message.
It made me miss the missing ENUM once the crash was gone.

Outliner: Fix crash for tooltips on ID operations

This was introduced on 9ca2cbdcea6a.

Outliner: Don't show id operations (make single user) when not supported

For the make single user operation to work we expect a parent of the
datablock to be around. However this is often not the case when not
accessing the data from Scenes or Viewlayer display modes.

For now we simply not show them in the other cases. They can be added
later though, by testing the outliner tree parent compatibility with the
expected parent id.

Subdiv: Tweak threading settings

Ensure that all threads on a multi-core system are used.

The issue was that BLI_task module was trying to be smart and
used heuristic to find optimal number of iterations per thread.
This heuristic assumes that tasks are light-weight, which is
not a case for subdivision surface.

On a higher subdivision level with a file from T70826 the
evaluation time goes down from 0.25 to 0.17 seconds per modifier
evaluation.

When D6189 is finalized we can being some extra performance
improvement.

Use mutex for lock in image.c

Usage of spinlock during heavy IO gave reduced performance
see D6267 for details.

Fix T69798: Pinning empty image objects

We have no dedicated image context tab, so for now making sure we don't
end up passing its ID as the pinned one.

If we ever get one, we then will need a different solution here, like
changing the ID that owns the data to be the object, instead of the
empty image datablock.

Python API: assume that a crashed Python operator returned FINISHED.

The CANCELLED return value from an operator is intended for
signaling that the operator aborted execution without changing
anything, and an Undo stack entry should not be created.

When a Python operator crashes, it is not safe to assume that
it did nothing, so it should interpret it as FINISHED instead.
Otherwise, the undo system behavior after an operator failure
feels broken.
