Alembic: nicer way to disable subdivision surfaces

Before exporting starts, subdivision surfaces are disabled. The old
Alembic exporter would do this temporarily for each frame.

Alembic: new mesh writer seems to work

Also extracted axis conversion functionality from `abc_utils.h`.

Fix T67232: Multiples targetless IKs in a chain gives weird behaviour (known as FakeIK for FK posing)

The issue was that the deps graph relation builder assumed that all
bones that had a IK constraint on them would be evaluated. However for
targetless IK bones, only the active bone would receive updates and the
others would be skipped (as those would be treated as if the IK
constraint was disabled).

I didn't see an easy way to solve this from the depsgraph side of
things.

Instead I came up with a solution that I feel is quite strait forward
and reflects what is actually supposed to happen under the hood.

Now all targetless IK constraints are treated as disabled and will not
be added to any relations in the depsgraph.

Instead, a temporary IK constraint will be created when the bone in
question is transformed. This is basically activating "Auto IK" for the
bone while transforming.

Fix T71546: VSE stereoscopic strips issues with mismatched dimensions

The issue is that the cachiing was adding the right view without the
proper pre-processed buffer.

Fix T75141: Default template versioning error for grease pencil

The versioning was done only for template because the code was after a return and never was executed for default scene.

Fix T74815: Shapekeys animation is blocked after second append of the same object.

Logic to handle shepkeys datablocks in helper in 'make local' code that
checks which ID should be copied, and which can be directly made local,
was wrong.

Test runner: On Linux, use Python from the precompiled libraries

CentOS on the buildbot still runs Python 3.6, which is also used for the
unit tests. This means that the tests can't use language features that are
available to Blender itself. And testing with a different version of Python
than will be used by the actual code seems like a bad idea to me.

Fix T74657: Grease Pencil Proportional Editing does not work for
'Individual Origins'

Note gpencil doesnt do anything fancy like meshes in
editmesh_islands_info_calc(), but it looks like there is actually no
harm in allowing proportional editing with individual origins & gpencil
editmode.

Pointclouds: fix point drawing

The radius component is only one float. This resulted in only a third of
intended points to draw and could lead to glitches.

Pointcloud drawing will still change a lot in the future, this is just
to be able to work on some simple tools.

Support displaying single checkbox for a value in split layouts

Mockup: F7430498.

This is technically quite difficult to support, due to how we create the
split layouts for each item. With this commit, layout creators should be
able to do it, even though it involves some boilerplate code. The
followup commit will demonstrate how it can be done.
