Fix T66967: skin modifier crash scaling skin radius to zero

Turn most flags in BlenderDefRNA into proper bool.

Cleanup: RNA: use `BlenderDefRNAtruct` named members initialization.

GPU: ShaderInterface: Refactor to setup all uniform at creation time

This remove the complexity of queriying the locations at runtime and
allows for more performance and upfront binding specifications.

The benefit of doing everything at creation time is that we can assign binding
points in a predictable order which is going to be somewhat the same for
every similar shader.

This also rewrite GPU_vertformat_from_shader to not use shaderface.

This is to keep the shaderface simple. If it becomes necessary to not query
the shader after creation (i.e: vulkan?) we could just create the vert
format in advance at compilation for PyGPU shaders.

GPU: Texture: Replace internal sampler state by explicit state object

This makes it easier to track as well as allowing us to sample the same
texture with different sampling parameters (which should fix the related
T73942 in the long run).

Cycles: Added shadow terminator offset parameter.

A new user parameter can be used to shift the shadow terminator
towards the light source. With it, one can hide some of the
artifacts that appear on coarse meshes with smooth shading.

Note that this technique is not engery conserving.

This is based on the work by the Appleseed renderer team.
