Cycles: implement transparent shadow continuation when max hits is reached

Only the CPU/Embree code is fully correct, for GPU it is not currently
guaranteed to find the N closest hits (although it is likely). That will
be solved next.

Pabellon renders identical to master with this change.

Fix BLO_library_temp_load_id loading temporary ID's into G.main

The intention with this API function was to temporarily load
ID's tagged LIB_TAG_TEMP_MAIN,
however the way the `real_main` was used,
these ID's were loaded into the G.main.

Cleanup: clang-format

Fix T87522: frame selected does not take instances into account

`ob->runtime.geometry_set_eval` can contain instances as well.

This only affected instances generated by geometry nodes.
We should probably have a separate function that tells us if an object
has instances or not..

Fix unreported: instances disappear when instanced mesh is in edit mode

The issue is that for historic reasons, `geometry_set_eval` does not contain
the mesh component when the object is in edit mode.

Remove unneeded code from previous commit.

Fix OCIO Shader Compilation Error.

Compilation fails when our OCIO wrapper creates a shader that
transfer first to scene ref and directly after that to display.
This cause is that the GPU resources of both transfers had the same
name. This is fixed by prefixing the resources.

This can be reproduced by loading a movie file (mkv) in the VSE editor.

Make constructors explicit.

Fix T87169: support attribute search on group nodes

Fix T87217: improve impact of seed in point distribute node

Incrementing the seed just by one did not mix things up enough.

Fix T87359: set group output in geometry node tree update callback

This also fixes T85511.

Fix T87441: don't remove custom attributes automatically

In the past, custom attributes were rarely used in practice, because the
only way to use them was from Python. Since geometry nodes, more
users started to add their own attributes. Those attributes should not
be removed automatically. It is still possible to remove them in
geometry nodes explictly to improve performance.

Fix T85691: attributes used by geometry nodes were removed automatically

This has technically been fixed by rB3e87d8a4315d794efff659e40f0bb9e34e2aec8a,
but the fix there is questionable, because it disables an optimization for vertex groups
entirely. This fix is a little bit more precise in that it only disables the optimization when
the object is used by some geometry nodes modifier.
