snippet: Add a hook for the layer texture coordinate transformation
This adds a hook called COGL_SNIPPET_HOOK_TEXTURE_COORD_TRANSFORM.
This can be used to alter the application of the layer user matrix to
a texture coordinate or it can bypass it altogether.
This is the first per-layer hook that affects the vertex shader state
so the patch includes the boilerplate needed to get that to work.
