Use better prng algo and fix randomness UI

Implement matcaps for hair

Gawain: Fix memory manager.

Eevee: fix some glsl for low quality lamps.

Mesh Batch Cache: get rid of the ORCO VBO data, and reconstruct it in shader.

With only one MADD instruction we recover the orco data and reduce both the storage and the fetching cost of an attrib layer.

Gawain: Add assert for maximum attribute name.

Gawain: Better metric for VRAM usage.

Mesh Batch Cache: Define Compressed format for shading data.

Deactivated by default.
All shading attribs can be packed to take less VRAM at the cost of precision (not noticable in this case).
UVs can be packed into I16 but that limits their positions into the [-1, +1] range.

This could be a setting option in the future.

Mesh Batch Cache: Optimization, make use of gawain attrib aliases.

Gawain: Add support for multiple attrib names.

This adds the possibility to give multiple name to the same attrib.
This allow multiple binding points depending on the shader.

Edit Mode Engine: Fix loose edges/verts not displaying.

Mesh Batch Cache: Split Edit Mesh mode Vertex Buffers for faster update.

Gawain: add short vector conversion to 10_10_10

Fix T50109: Blender crash when a "Render Result" as a Texture

This commit fixes crash, but user feedback can be improved here to
inform artist that one can't use Render Result as a texture since that
will cause feedback loop.

Fix T49324: True displacement crashes when shader returns NaN

Fix T51348: Node highlighting is broken

This feature was disabled in the code but not in the interface.

Removing the code, since it needs full re-implementation anyway.

Fix T51501: Cycles baking cancel affects baking script

Basically upon invoking cycles baking we could canell it which would
leave G.is_break hanging as true. Since we were not setting is_break to
false before exec baking, it would misbehave.

Add show-weights to edit-mode UI

Fix T51180: BMesh crash using calc_uvs=True

Don't assume UV layer exist.
