Move the `StaticShader` class from Workbench to `GPU_shader` and make compilation thread-safe (Shader usage is still not thread-safe). Use `StaticShader`s for all shader caches. Subdivision shaders are still not ported. (Part of #134690) Pull Request: https://projects.blender.org/blender/blender/pulls/134812
