Fix T77734: random crash when rendering animation

Differential Revision: https://developer.blender.org/D7986

Fix T66934 Overlay: "Outline Selected" overlay doesnt affect armatures

This is a really small fix. Could be included in 2.83 LTS branch.

Fix: Crash when closing window while Outliner shows screens

Steps to reproduce were:
* From factory settings, change Outliner Display Mode to "Blender File"
* Open "Screens" item, make sure all listed screens are visible
* Open Preference window, close it
* Mouse hover the outliner -> crash

Fix is to force an Outliner tree rebuild when closing screens.

Fix T77328: Crash on undo Draw Face Sets stroke with dyntopo active

Draw Face Sets does not work in Dyntopo and the sculpt API should be
responsible for that without needing to add checks all over the code,
but it was doing an undo push of type SCULPT_UNDO_FACE_SETS which is not
supported, causing the crash.

Fix T77754: Crash after any alembic import undo in an empty scene

Thanks @mont29 for this patch.

This creates an explicit undo step after the Alembic importer has finished
running. This is necessary when the importer runs as a background job.

Fix T77712: Crash on proxied rig, custom bone shape, driver targeting rig

It turns out that
`DepsgraphNodeBuilder::build_object_data_geometry(Object *object, bool
is_object_visible)` was called for the custom shape with
`is_object_visible=false` when there are drivers, and
`is_object_visible=true` when there aren't any.

Fix T77830: Crash in VR session when opening material preview

Draw-manager mutex has to be set before activating OpenGL/GPU context.
Otherwise, parallel jobs (like preview rendering) may try to activate
the context from another thread.

Also: Use WM wrappers for activating/releasing OpenGL context, which
have an additional assert check.

Suggest to backport this for 2.83.1.

The region refresh callback wasn't called, which in the VSE ensures valid

Fix T67358: Compositor Disabled Node Config -> SegFault

The issue was caused by wrong conversion happening after some of the
proxies are removed. Easiest solution is to first remove proxies and
then add required converter operations.

Thanks Jeroen for the review!

Outliner: Draw collection hierarchy lines

Rather than drawing lines for object hierarchies, draw for collections.
These lines will be colored when collections are colored.

There are still small issues with the implementation, but it works quite
well for now.

The dashed lines for child objects (not in collection) are removed but
could be brought back.

Fix: Add drag lock to mode column icons

Allow "sloppy" drag over the column

Outliner: Draw collection color behind icon

Rather than coloring the icon itself and drawing a bar to the left, draw
a roundbox behind the collection icon. This has the benefit of being
small but still easily noticed.

Two downsides that need to be addressed:
1. The active collection highlight is not shown. This needs to be
refactored anyway for all types because it is not always easy to tell
which items are active.
2. Hierarchies are not colored.

Mode Column: Move collection checkbox to mode column

To make the hierarchy more clear, draw the collection exclude icons in
the left column. While this is nice, it makes the mode toggle column
very messy in non-object modes. Will look into that later.

Outliner: Remove data activation columns

This column is no longer part of the plan.
