clutter: Drop LayerNode.new constructor

Browse Source 
My motivation was at first to replace cairo_rectangle_t with graphene_rect_t
but noticed nothing uses it anywhere: Shell/Kiosk/Gala; so it is safe
to just drop and people could still use the new_to_framebuffer ctor
and handle setting up things themselves if needed.
