Properly set the number of components on the CoglTextureRectangle

Browse Source 
We need to set the number of components on the CoglTextureRectangle to
prevent wasting too much GPU memory. As we need to do this before we call
cogl_texture_set_region, just remove the meta_texture_rectangle_new wrapper,
and make callers call cogl_texture_rectangle_new_with_size directly.
