cleanup, encapsulate ProceduralManager

cleanup, includes

make sure code compiles without alembic

alembic: check that we indeed have animated transformations

Cleanup: De-duplicate object mullptr checks

Makes it more clear whether object is allowed or not allowed to be NULL.
Also, avoids possible access to the different object mode enumerator.

Should be no functional changes.

cleanup: remove some parameters from IObject reading functions

Fix T83275: Crash with scene statics and empty scene

ob can be NULL, so it needs to be checked before accessing ob->mode

procedural: add Progress to generate

Merge branch 'master' into cycles_procedural_api

Cleanup: Store "is_active" instead of pointer property in panel type

This is consistent with the way other panel type fields are stored.

Fix sculpt transform incorrently flipping displacement in Y and Z axis

These functions were only checking the X axis for flipping the
displacement for a symmetry area depending on the initial position of
the pivot.
This affects transform and any other tools that transform vertices and
applies symmetry based on areas (the pose brush, for example).

Merge branch 'master' into geometry-nodes

UI: Add Sculpt Session info to stats

This adds the vertex and face count info to the scene stats in sculpt
mode. These stats count the active vertices and faces in the
sculptsession for the active object. This has the following advantages:
- It is possible to know how many vertices the sculptsession has active
comparted to the vertex count of the entire scene from sculpt mode
- When sculpting with constructive modifiers, these stats will report the
number of vertices that you can actually sculpt with, instead of the
vertex count of the modified mesh and the entire scene.

Cleanup: Use LISTBASE_FOREACH for node tree sockets RNA code

Resolved merge conflict, reformatted, break long lines, parameters

Importer Cleanup: renames, const.

Merge remote-tracking branch 'origin/master' into geometry-nodes

Cleanup: Reduce variable scope in node drawing code

Also use LISTBASE_FOREACH in a few places and generally clean up
the code for the two sidebar panels "Sockets" and "Interface".

Cleanup: Remove unecessary code.

We already `memset` the whole mesh runtime to zero, no need to set some
of its pointer explicitly to NULL afterward.

Fix T83196: bad matrix to quaternion precision near 180 degrees rotation.

Adjust the threshold for switching from the base case to trace > 0,
based on very similar example code from www.euclideanspace.com to
avoid float precision issues when trace is close to -1.

Also, remove conversions to and from double, because using double
here doesn't really have benefit, especially with the new threshold.

Finally, add quaternion-matrix-quaternion round trip tests with
full coverage for all 4 branches.
