Fix T76740: Static Override - Library Override Crash

Missing proper tagging of 'backward' pointer from fcurve to its group in
RNA would lead to infinite loop...

Issue was triggered by override, but crash could be generated from other
places as well (like from py console), on any action actually...

Fix T76738: Duplicate brushes cause assertion on undo

Fix duplicate ID's being created when appending/linking

This removes grease pencil brush creation/dat-block delete on load,
since this causes duplicate data-blocks.

Add assert to prevent this happening in the future
since the error is isn't obvious.

Fix error versioning paint-slots pre-2.80

Cleanup: don't check flags as booleans

Causes unexpected behavior when adding new flags.

Cycles: Refactor microfacet BSDFs to remove separate anisotropy code

Since the sampling and evaluation functions handle both cases anyways,
there's not really a point for keeping the distinction in the kernel,
so we might as well cut down the number of CLOSURE_BSDF_MICROFACETs a bit.

GPencil: Add licence text at header

Fix T76025: Flip/recalc steep custom normals produces wrong result

The issue was the custom loop normal data would be mangled when we
reversed the face loops.

The flip face code will now correctly flip the custom face normals so
they are not left in an undefined state.

Fix missing hinting information in default font

Fix T76476 EEVEE: Invalid Vector to Float conversion for nodegroups

The previous code only handled the RGBA socket case. For vectors, we simply
use the average of the 3 compoments. This is done using a temp Vector Math
node using the dot operation.
