Sculpt: Fixed tooltips for brush channes in RNA

* BrushChannel now uses its refine callback to
generate new structs for individual BrushChannelType's.
- It generates a .value member that's a copy of
one of the exisitng float_ bool_ enum_ etc_value members.
- Haven't figured out how to delete the XXX_value members
yet though.

Fix T91803: Freestyle rendering as pass broken after recent changes

Fix missing passes result when rendering multiple views

Caused by the lazily pass pixels allocation which didn't reset
allocation state of the render result.

Sculpt: Drag dot fixes

* Drag dot now uses anchored's method
of calculating brush rake angle, this
is much more usable and less numerically
unstable.

* There is now an option ("Smooth Raking" to
smooth rake angles during brushes. This was
a failed effort at fixing drag dot raking
that turned out to be useful for other things.

* Drag dot no longer requests subspacing events
from the brush system. This made a huge
difference in performance and is now on par
with anchored mode.

Viewport Compositor: Fix compositing multiple viewlayers from one scene

All layers were not correctly rendered or using the right index.

Sculpt: fix compile error

GCC is giving errors on assigning
integers to char arrays. Naturally
this makes sense, and of course MSVC
doesn't even have a warning to detect
this (I tried enabling them all).

I may go back to clang.

Remove ATTR_NO_OPTs

Viewport Compositor: Improve update mechanism

Now viewport updates fully through DRWRenderScene even if compositor
is disabled.

External RenderEngine now have the correct depsgraph during update.

Changes based on review by Hans Goudey (HooglyBoogly)

Merge branch 'master' into soc-2021-curves

Cleanup and refactoring

move node_common to c++

Viewport Compositor: Move `rv3d->render_engine` to `DRWRenderScene`

This allows multiple instances of external render engines per viewport.
Allowing them to be combined by the compositor.

Many things needed to be ported to the draw manager since it is the only
one that can know what is inside the `DRWRenderScene` and can iterate
over all running engines.

Merge branch 'master' into tracking_tools

fix compiler error

Sculpt: fix drag-dot/anchored for face sets

* Added an API for original face sets
based on the SculptCustomLayer API.
