lavc: Add h264_redundant_pps bitstream filter
This applies a specific fixup to some Blu-ray streams which contain
redundant PPSs modifying irrelevant parameters of the stream which
confuse other transformations which require correct extradata.
A new single global PPS is created, and all of the redundant PPSs
within the stream are removed.
(cherry picked from commit e6874bc3af2f09af39b5d91b9c5f9ded67459696)
