compositor: Add a WESTON_PAINT_NODE_BUFFER_PARAMS_DIRTY

Browse source 
This already existed for surface, so it is trivial to add.

This will let the upcoming plane state reuse code notice a format change.

This is handy because a client might respond to dmabuf feedback by changing
formats, with the expectation that doing so would land content on a plane.
