Cleanup: reduce indentation in bpy.props

Remove unnecessary NULL checks.

Fix menu poll function being ignored for UILayout.menu

Using `UILayout.menu()` [1] or `UILayout.menu_contents() [2], the menu
would just always be added, the `poll()` check not being executed. As
API user I would expect the `poll()` to deterimine visiblity of the
menu.

Fix Cycles crash with fluid object motion blur disabled

Motion attributes expects mesh to have non-zero number of motion steps,
which was violated in the case when fluid mesh had motion blur disabled.

This is a bit of annoying fix, because of the order of updates. More
ideal solution would be to handle cached and fluid velocities in the
sync_mesh_motion() which ensures all the dependencies between settings.

Cycles: remove WITH_CYCLES_DEBUG, add WITH_CYCLES_DEBUG_NAN

WITH_CYCLES_DEBUG was used for rendering BVH debugging passes. But since we
mainly use Embree an OptiX now, this information is no longer important.

WITH_CYCLES_DEBUG_NAN will enable additional checks for NaNs and invalid values
in the kernel, for Cycles developers. Previously these asserts where enabled in
all debug builds, but this is too likely to crash Blender in scenes that render
fine regardless of the NaNs. So this is behind a CMake option now.

Fixes T90240

BlenRead: Add GHash-based search for already read linked IDs.

Ths commit adds a new `IDNameLibMap` to `Main`, used during file reading
to quickly find already read linked IDs.

Without that, search would use string-based search over list of linked
data, which becomes extremely slow and inneficient in cases where a lot
of IDs are linked from a same library. See also {T89194}.

Extrem-usecase reported in T89194 is now about 4 times faster in linked
data reading (about 2 times faster for the whole .blend file loading).

More normal cases (like Sprites studio production files) have barely
measurable speed improvements, a few percents at best.

NOTE: `main_idmap` API was extended to support insertion and removal of
IDs from the mapping, avoids having to re-create the whole thing several
time during libraries expansion in readcode.

Fix building without Cycles logging

Ideally can use assert() checks instead of suppressing the check entirely,
but for now just fix compilation error quickly.

Regression Testing: Running tests based on blend files

Runs tests based on blend files with minimum python interaction.
Developed as part of GSoC 2021 - Regression Testing of Geometry Nodes.
Earlier, tests were built from scratch by adding a modifier/operation
from the Python API.
Now, tests can also be created inside blender and are compared using
Python script.

Features: Automatically adding expected object if it doesn't exist.
This patch adds tests for the following Geometry Nodes category:
* Curves
* Geometry
* Mesh
* Points

The implemented UML diagram for refactoring of mesh test framework.
{F10225906}

Technical Changes:
SpecMeshTest: It adds the modifier/operation based on the Spec provided.
BlendFileTest: It applies already existing modifier/operation from the blend file.

Test folders hierarchy with tests. This folder should be extracted to `libtestsmodeling`
{F10240651}
Note: The `geometry_nodes` folder might lie under another `geometry_nodes` folder while extracting, please double check. Use the inner-most one.
The hierarchy should be:
-`libtestsmodelinggeometry_nodesmesh`
-`libtestsmodelinggeometry_nodespoints`
and so on.

* From `ctest` the tests should be run as `ctest -R geo_node -C [Configuration]` on Windows.
* Each single test can be run with its entire name e..g `ctest -R geo_node_geometry_join_geometry`.(just an example). Run `ctest -N -R geo_node` to see all tests.
* From blender, the tests can be run `blender -b pathtoblendfile --python pathtogeo_node_test.py`

Remove the code in `BKE_collection_move` to preserve LayerCollection flags.

This code was actually buggy (forcefully re-enabling excluded layers in some
cases).

Further more, it should not be needed now that layerCollection resync code
reuses as much as possible existing layers instead of deleting and
re-creating them all the time.

Fix T89415: update multi input indices after deleting a node

When deleting a node, links attached to that node are deleted, but if one
of those links was connected to a multi input socket, the indices of the
other links connected to it were not updated. This adds updates both in
the case of a normal delete as well as after a delete with reconnect.
