clutter/paint-node: Expose clutter_paint_node_get_framebuffer()

Browse Source 
Mutter needs to know which framebuffer the paint nodes will be
drawn into, and using cogl_get_draw_framebuffer() directly is
not an option since ClutterRootNode only pushes the draw fb
at draw time.

Expose clutter_paint_node_get_framebuffer().
