Cycles: add per layer collection mask/holdout support.

In the outliner, right click > view layer > set holdout. This is
temporary until we have more general dynamic overrides, but helps
Spring production for now.

Cleanup: mark missing Cycles view layer override features with TODO.

UI: Dynamic Paint single column and sub panels

UI: Hide snap options in Paint, Sculpt and Weight mode

UI: Remove duplicated menu items

Some options were duplicated by error in previous commit.

UI: Node Editor Properties single column

Color and Properties panels as sub-panels of Node. Collapse Node properties
by default, since they are already in the node itself and in material properties.

Fix T55895: VSE crash while moving a strip

Glitch from multi-edit project. ;)

UI: Texture Properties Layout and Cleanup

Initial work on single column layout, flow and organization of
the texture properties. More work needs to be done in the C templates
for image textures.

See D3557

Annotation Eraser: Only erase the point within the cursor, not the whole segment

varying colors.

Support for sync selection switching which keys apply.
