GPUShaderCreateInfo for interface abstraction

This is a first part of the Shader Create Info system could be.

A shader create info provides a way to define shader structure, resources
and interfaces. This makes for a quick way to provide backend agnostic
binding informations while also making shader variations easy to declare.

- Clear source input (only one file). Cleans up the GPU api since we can create a
  shader from one descriptor
- Resources and interfaces are generated by the backend (much simpler than parsing).
- Bindings are explicit from position in the array.
- GPUShaderInterface becomes a trivial translation of enums and string copy.
- No external dependency to third party lib.
- Cleaner code, less fragmentation of resources in several libs.
- Easy to modify / extend at runtime.
- no parser involve, very easy to code.
- Does not hold any data, can be static and kept on disc.
- Could hold precompiled bytecode for static shaders.

This also includes a new global dependency system.
GLSL shaders can include other sources by using #pragma BLENDER_REQUIRE(...).

This patch already migrated several builtin shaders. Other shaders should be migrated
one at a time, and could be done inside master.

There is a new compile directive `WITH_GPU_SHADER_BUILDER` this is an optional
directive for linting shaders to increase turn around time.

What is remaining:
- pyGPU API {T94975}
- Migration of other shaders. This could be a community effort.
