Update the `ShaderCompilerGeneric` to support deferred compilation using the batch compilation API, so we can get rid of `drw_manager_shader`. This approach also allows supporting non-blocking compilation for static shaders. This shouldn't cause any behavior changes at the moment, since batch compilation is not yet used when parallel compilation is disabled. This adds a `GPUWorker` and a `GPUSecondaryContext` as an easy to use wrapper for managing secondary GPU contexts.
