avcodec/dovi_rpu: expose guess_profile(), clarify semantics
To allow internally re-using it for both the encoder and decoder.
This is based on HEVC only, H.264/AV1 use their own (hopefully correctly
signalled) profiles (and in particular, the AV1 decoders implicitly
default the correct profile in the absence of a configuration record).
