gpu: Add gsk_gpu_node_processor_add_first_node()

Browse Source 
Asks a node to add itself if it is fully covering the clip rectangle.
In that case, it is the first node that needs to be added.

If the node is not fully covering the clip, it should not draw itself,
because there might be stuff needing to be drawn below.

If a node adds itself, it should call gsk_gpu_render_pass_begin_op().
