Cycles: Display RenderPass in Viewport

This change allows the user to select a renderpass in the 3d viewport.

Added support for external renderers to extend the `View3DShading` struct.
This way Blender doesn't need to know the features an external render engine wants to support.
Note that the View3DShading is also available in the scene->display.shading; although this is
supported, it does not make sense for render engines to put something here as it is really
scene/workbench related.

Currently cycles assumes that it always needs to calculate the combined pass; it ignores the
`pass_flag` in KernelFilm. We could optimize this but that was not in scope of this change

Armature: convert the length Python property of bones to a RNA property.

This allows accessing it from drivers and using it in UI, as
demonstrated by adding it to the transform panel of 3D View.

As an aside, properly mark transform-related properties of Bone
read-only, as they can only be changed correctly in edit mode.

Depsgraph: Allow non-keyed changes from frame_change_post handler

Render: Only run callbacks for non-preview renders

Those handlers are usually done to edit scene which is being rendered,
and this is not supported due to a fully localized nature of the preview
bmain.

There is still non-conditional callback in stats_background which is a
bit tricky to cover with check, but this code is not supposed to be run
for previews anyway.

Python handlers: Pass depsgraph to events where it makes sense

The goal is to make it possible to access evaluated datablocks at a
corresponding context. For example, be able to check evaluated state
if an object used for rendering.

Allows to write scripts in a safe manner for T63548 and T60094.

Depsgraph: Introduce depsgraph registry

Allows to access dependency graphs created for render engines
to inform them about changes in .blend file structure from the
Python handlers.

Depsgraph: Pass bmain to depsgraph object creation

Currently unused, but will allow to keep of an owner of the depsgraph.

Could also simplify other APIs in the future by avoiding to pass bmain
explicitly to relation update functions and things like that.

Transform: Snap: Fix mixed snap without edge

Face snapping was disregarded when approaching an edge.

UI: File browser deselect on click on empty space

For the default and industry compatible keymap, clicking on empty space
in the file browser will deselect all files.

Also makes selection use same operator description we use for other
select operators.

Fix SDNA error expanding names not updating name array sizes
