James Almer 0d487be837 avcodec/libdav1d: don't depend on the event flags API to init sequence params the first time
A bug was found in dav1d <= 1.0.0 where the event flag New Sequence Header would
not be signaled for some samples using delayed random access points.
It has since been fixed, but nonetheless it's best to ensure the AVCodecContext
is filled with parameters when parsing the first frame, regardless of what events
were signaled.

Fixes ticket #9694.
