avcodec/decode: add an internal codec flag to signal a decoder sets all output frame properties

Browse Source 
Decoders like cuviddec ignore and overwrite all the properties set by the generic
code as derived from AVCodecInternal.last_pkt_props. This flag ensures libavcodec
will not store and potentially queue input packets that ultimately will not be used.
