Add missing Shader FX remapping to library query

Workbench: Add "Shadow" factor to Xray

This just maintain more parity accross the 2 visuals. Note that this is not
"real shadowing" just the facing factor shadowing.

Workbench: Add transparency support for materials

This adds the posibility of having certain materials transparent in solid
mode. The option is (for now) per material only and thus only shows in
material color mode.

This uses the same rendering technique as Xray mode.

Note that objects are not considered transparent for selection with this.

Object Mode: Fix reading past buffer end when drawing camera

Workbench: Depth Of Field: Improve noise and Large radius

- Add noise to remove undersampling artifact
- Create 2 mipmaps to the scene color buffer in order to have bigger blurs
- Replace blur2 with a 3x3 median filter that doesn't dilate the highlights
- Use temporal accumulation to remove noise

For some reason all of this exacerbate some bleeding issues happening on
far foreground elements from near foreground elements. The actual problem
was already happening before but was not really noticeable. It needs some
more work to be fixed.

Fix duplicate brushes from recent startup files

Default versioning caused duplicates when the startup was re-saved.

Fix T60226: Inset not working well on very small faces

The inset operator uses 0.01 as default for the inset.
When the face is very small than this default is very confusing (see T60226).

The simplest fix seems to be to just use 0 as default.
This is similar to the extrude operator which uses 0 as default as well.

Bevel - better corner shapes for inner arc miters.

The subdivision method for getting corner shapes has a fullness
parameter which had been set by eye before. This change uses fullness
as found by offline search process to best match the superellipsoid
octant in the cube corner case (except cube corner case is still handled
by other code). This somewhat improves the look of cube corners with
inner arc miters, however.

Caused T58284

Cycles: Moved feature overrides to Simplify subcategory

Cycles: Polygon smoothing feature override now properly updates in viewport

ignore weights <= 0

use uint

Fix T59924: Blender 2.8 particle system error

Was missing relation from particle keyed targets to the
particle system, which caused some race conditions.

DRW: support clipping for all lamp types

Cycles: Moved most feature override code to host side to keep kernel code simple

Fix CLOG_STR_AT_SEVERITY macro

Part of D4277 by @sobakasu

Fix duplicate brushes being added to startup

All builtin templates have this brush.

Fix T60809: Crash undoing object rename in edit-mode

Currently names are used for edit-mode undo-steps,
any changes to Main ID names cause lookup failure (crashing).

This commit ensures any undo steps that use ID lookups have the same
mem-file undo state loaded that was used to encode the steps.

Renaming also has an undo push added (last commit).
