Render: move Cycles visibility, holdout and shadow catcher properties to Blender

The immediate reason for this is that we want to be able to initialize them
to different defaults for light objects, which is hard with Python properties.
But in general it is useful to be able to share these with other renderers.

As a side effect, Eevee now supports a per-object holdout instead of only
per-collection.

Cleanup/Fix RNA array length accessors returning non-zero values in invalid cases.

This was apparently done in two places only, with a very cryptic comment
(`/* for raw_access, untested */`), and... I cannot see how returning a
non-zero length value for an array that does not exist or is not
accessible at least, would be anything but an obvious source of issues.

Note that both commits adding those lines are from stone ages (2009):
rBcbc2c1886dee and rB50e3bb7f5f34.

Fix T83164: Spline IK `joint_bindings` parameter is broken.

Code freeing the array would not properly reset its length value to
zero.

Note that this corrupted data could also be saved in .blend files, so
had to bump fileversion and add some doversion code too.

Fix T90166: crash when creating a liboverride.

Cycles X: Silence OIDN denoising cancel message

Cancel is considered to be an error by the OIDN library, but we do
cancel to keep viewport interactive and this is not an error as far
as we are concerned.

Cycles X: refactor passes to work like other nodes in the scene

* Alloc through create_node<Pass>() instead of Pass::add().
* Handle auto adding of passes, duplicate removal and other validation
in update_pass(), afterwards.
* Centralize pass logic from scene.cpp and pass.cpp into film.cpp.
* Move logic for which passes are read/written or noisy/denoised out
of Blender sync.
* Eliminate or change DENOISED to NOISY passes when denoising is
disabled, rather than using is_written().

This makes some upcoming changes easier, and is also a step towards
a better Cycles public API.

Cycles X: More flexible OIDN prefiltering settings

Allows to bring back old behavior when color and guiding passes are
denoised at the same time. Exposed as a single enum, so that we only
expose combinations which makes sense from configuration perspective.

Possibilities are:

- None. Assumes that the guiding passes are clean. Gives best results
without extra processing time (in expense of requiring to have enough
samples rendered to give clean guiding passes).

Corresponds to OIDN cleanAux=true and no prefiltering done on the
guiding passes.

- Fast. Old behavior, color and guiiding passes are denoised together.
This is fastest way of giving denoised result, in the expense of
possible loss of details.

Corresponds to OIDN cleanAux=false and no prefiltering.

- Accurate. Use special guiding passes prefilteringbefore denoising
color passes. Gives best results in the expense of extra time needed
to perform prefiltering. Avoids over-blurring details.

Corresponds to OIDN cleanAux=true and prefiltering performed on the
guiding passes.

XR Controller Support Step 2: Action Maps

Addresses the remaining portions of T77137 (Python API for Controller
Interaction), which was partially completed by D10942.

Adds an XR "action maps" system for loading XR action data from a
Python script. Action maps are accessible via the Python API, and are used
to pass default actions to the VR session during the
xr_session_start_pre() callback.

Since action maps are stored only as runtime data, they will be
cleaned up with the rest of the VR runtime data on file read or exit.

Bug fix: error when selecting NURBS spline

Fix T89963: crash when library override is applied to an object from a linked scene.

LibOverride of scenes is not really supported currently, there are many
issues with it.

Will disable most user-accessible ways to create such overrides in a
following commit.

LibOverride: Make it reasonably impossible for users to create overrides of scenes.

This is not supported currently,doing so through RNA API remains
possible, but from regular UI operations it should not be doable
anymore.
