Sculpt: Delay Viewport Updates

In Blender 2.81 we update and draw all nodes inside the view planes.
When navigating with a pen tablet after an operation that tags the whole
mesh to update (like undo or inverting the mask), this introduces some
lag as nodes are updating when they enter the view. The viewport is not
fully responsive again until all nodes have entered the view after the
operation.

This commit delays nodes updates until the view navigation stops, so the
viewport navigation is always fully responsive. This introduces some
artifacts while navigating, so it can be disabled if you don't want to
see them.

I'm storing the update planes in the PBVH. This way I can add support
for some tools to update in real-time only the nodes inside this plane
while running the operator, like the mesh filter.

VR: Refactor DirectX context management

All DirectX management happens on Ghost level now, higher level code can
just assume everything is OpenGL (except of the upside-down drawing that
still needs to be done for DirectX). This is similar to how the
metal-layer is hidden outside of Ghost.

The Ghost-XR graphics binding for DirectX is responsible for managing
the DirectX compatibility now.

Sculpt: Add global automasking options for all brushes

This adds the automasking options to the Sculpt Tool options in a way
that they affect all brushes. This is more convenient when working with
some of these options while switching brushes as they don't need to be
enabled/disabled per brush.
An automasking option is enabled if it is enabled in the brush or in the
sculpt options.

Fix T74983: Material preview icons don't refresh

The root cause of the issue reported in T74983 is that an `IDNode` would
not be marked as user-modified. This marking happened while looping over
outgoing relations of one of its operation nodes. Since rBff60dd8b18ed
unused relations are removed, and as a result the `IDNode` would not be
marked.

The solution was to move the responsible code outside the loop; this is
probably a good idea anyway, as the code did not actually use the
looped-over relations at all, and was thus repeated unnecessarily.

Scultp: Face Set boundary automasking

With this brush option it is possible to mask the boundary vertices of
all face sets. This is especially useful in the cloth brush, where face
sets can be used to simulate seams between different patches of cloth
and produce different patterns and effects.

Fix Face Sets painting and selection precision

This fixes the following issues:
- Previously, the face set from the active vertex was used directly. Vertices always return the most recently created face set, so in some cases there may be some face sets that were not possible to select as active. Now the active face set is set in the ray intersection, so it always matches the face under the cursor.
- When drawing face sets they were set per vertex, so it was not possible to paint one face at a time. Now face sets are painted per poly when using the brush on meshes, testing the distance to the center of each poly.
- The code for the active vertex on PBVH_GRIDS was not correct, so I also fixed that to test if everything was working correctly.

Fix mesh boundary automask curve falloff
