Fix T74220 Mantaflow Color Mapping not ignoring alpha value

And also remove some sRGB hack.

Fix T61573 GPencil: Annotation thickness doesn't work with on OSX

This fixes the issue by using the polyline shader but this does not gives
the best results.

A better way would be to have a dedicated shader for the lines to avoid
the line break at every angle change.

Build: Point ISPC explicitly to the location of LLVM libraries.

Sometimes the ISPC build could pick up the system LLVM librareis
instead of the ones in the Blender lib directory.

Fix compiler warning for deprecated variable use

Cleanup: minor change missed last commit

Cleanup: use designated initializes for mesh extract structs

Better readability and allows adding new struct members without
adding empty slots to every 'MeshExtract' struct.

Cleanup: use std::make_unique instead of blender::make_unique

This is possible, because we use C++17 now.

Fix T73892: EEVEE Viewport Render Ignores Render As Wire

In the viewport an object can be set to be displayed as wire. When

when rendering a viewport render.
