Frank Plowman b0c77e5a12 lavc/vvc: Store RefStruct references to referenced PSs/headers in slice ...

This loosens the coupling between CBS and the decoder by no longer using
CodedBitstreamH266Context (containing the most recently parsed PSs & PH)
to retrieve the PSs & PH in the decoder. Doing so is beneficial in two
ways:
1. It improves robustness to the case in which an AVPacket doesn't
   contain precisely one PU.
2. It allows the decoder parameter set manager to properly handle the
   case in which a single PU (erroneously) contains conflicting
   parameter sets.
