Merge remote-tracking branch 'origin/master' into temp-lineart-contained

Sculpt: More brush channels stuff

Small progress towards outputting attributes from modifier

Sculpt: Unnest channels.channels in RNA

* BrushChannelSet is now a pure collection. This
eliminated the annoying brush.channels.channels
paths, and also makes library overriding work.
* Now sure I've done this correctly. Struct extended
collection properties are a bit confusing.

Merge branch 'master' into temp-asset-browser-catalogs-ui

Properly null-check the asset catalog tree before accessing for UI

Assets: Read catalogs immediately when loading a library

Until now, the asset catalogs would only show up after all assets from
the library were loaded. Now the catalogs are read first, which makes
them appear pretty much immediately.

I added a dedicated file-list type for asset libraries now. While not
necessarily needed, I prefer that so asset library specific stuff can be
handled in there.

USD IO improved feedback.

Now parsing the Python notification dictionary object
returned by UMM to output warnings and error to the
Blender log.

Removing unneeded log message when setting the
default prim, as it can obscure more important
warnings and errors in the status bar.
