75538bbc9b decoder: use POC to maintain the DPB. 
Introduce a POC field in GstVaapiPicture so that to store simpler sequential
numbers. A signed 32-bit integer should be enough for 1 year of continuous
video streaming at 60 Hz.

Use this new POC value to maintain the DPB, instead of 64-bit timestamps.
This also aligns with H.264 that will be migrated to GstVaapiDpb infrastructure.

ac4fc0d36c mpeg2: add new decoded picture buffer infrastructure. 
Decoded pictures are now maintained into DPB, similarly to H.264.
The same mechanism could be re-used for VC-1 and MPEG-4:2 codecs.
