Viewport Compositor: Support multiple render layers

This adds the new DRWRenderScene structure (and its sub structures) that
contains all the needed render passes for each scene present in the
compositor nodetree.

The scenes are rendered using a special option to avoid rendering overlays.

The render layer input to the GPUMaterial are now a separate structure and
a separate list of input handled by the compositor engine.

Rendering all scenes is the first thing done to avoir much trouble with

There are still issues like continuous rendering of TAA because the same
DRWData is used for all scenes.

Viewport Compositor: Separate the compositor checkbox to its own tab

This is to make is visible under all engines.

Merge branch 'master' into tracking_tools

Fix T91679: Crash when saving bordered render as multilayer exr

The related issue which is fixed by this change is the missing noisy
image pass when denoising and border render is used,

Need to allocate passes after the passes has been copied from the
original render result.

This is a manual cherry-pick of rB741fa8180c4f.

Increase VSE strip channels limit from 32 to 128

The original limit dates back from 2002 when Blender went open source.
After that many years some productions (e.g., Sprite Fright) are already
experiencing limitations for complex edits.

The future plans is to support an initial shorter (2?) number of
channels with support to "unlimited" channels.

Finally, I'm bumping the minimum file requirement since files with more
than 32 channels won't work well in old Blender versions.

In a future commit I will implement a sanitization so that we only read (and write)
128 channels. Making sure future changes of this number won't corrupt Blender.

Let UI show the active default catalog

Basically, rather than only letting the UI code set a new active
catalog, also always check what the current value is when constructing
the tree.
This makes the "All" catalog selected by default, but also let's the UI
update properly if the active catalog is changed from the outside (e.g.
via BPY).

Sync to master

The added files were not intended to be committed/pushed. And apparently
there's a leftover from a merge conflict.

Asset Catalog Tests: unnecessary use of temp dir

Remove unnecessary use of temp directories in the Asset Catalog unit
tests, so that the test doesn't try and clean up a directory that
doesn't exist.

Add '+' icon for "All" item to allow adding top-level items

Before this, there was no way to create a catalog tree from scratch, or
to add new top-level items.
