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.
