Cycles X: Cache result of scene's has shadow catcher test

The scene is tagged for an update of the flag from object's update tag.
Currently not following the typical nodes update because of couple of
reasons:

- Scene is not a node, and object manager does not store any state at
this time.

- The access to the flag could happen before scene device update.

Added test file for Geometry Nodes

Cycles X: Reduce memory usage of OptiX denoiser

The idea is to perform denoising in the render buffer's denoised pass
without allocating temporary color.

This optimization covers all scenarios of when OptiX denoiser is used:
single- and multi- device rendering.

The change is a bit bigger than it could be from the minimal functional
point of view, but kept running into some issues and seemed helpful to
make certain parts more clear.

Fix cycles crash when changing viewport display pass

It was possible that render buffers and scene kernel data will be out
of sync because reset and scene update happens in different locks.

This is similar issue we've fixed in the Cycles X branch, so backported
relevant changes from there.

This change removes what seems to be unused feature kernel.

Tracking: Fix "Lock to Selection" option from header causing jump

This change makes the behavior consistent between shortcut and
option from space clip's header.

The only caveat is that the "Lock to Selection" is removed from the
Display popover. This is because it is rather hard to make operator
to render same as regular checkbox. However, shouldn't be a problem
because the setting in popover was redundant.

Fix typo in Fly mode tooltip

The bug was always around and was introduced with the original code
e2a7168e9680f (2009).

Renamed Limittypes from Face to Border and from Edge to Selection
because you can use them with different domains and the real difference
is how it uses this data.

More renaming.

Rename to ShaderBlocks
