Add extra input validation to RtpFrameReferenceFinder for codec-specific cases

wrap ids before unwrapping: should be noop for ids arrived from the
network, but avoids DCHECKs for ids arrived from fuzzer.

for vp9 double check number of references doesn't exceed maximum.
for vp8 drop key frames for non-zero temporal id.
for general by seqnum code path do not set last_picture_id_:
it is not used there, but may confuse vp8 codepath.

as a slight speed up avoid copying RTPVideoTypeHeader for vp8 and vp9.
