compositor: Improve timing information in scene graph dump

Browse source 
After moving the drm-backend's scene graph dump, it now always occurs when
repaint_status is REPAINT_AWAITING_COMPLETION, which loses useful timing
information we used to have.

Add timing information for the REPAINT_AWAITING_COMPLETION state, and also
add the expected presentation time.
