With video_signal_type_present_flag set but colour_description_present_flag
unset the colour fields would not have had their correct values inferred.
(cherry picked from commit f9b8503639)
In scearios where a Temporal Unit is written right after reading it using the same
CBS context (av1_metadata, av1_frame_merge, etc), the reference frame state used
by the writer must not be the state that's the result of the reader having already
parsed the current frame in question.
This fixes writing Switch frames, and frames using short ref signaling.
