BACKPORT: media: venus: hfi_parser: Add check for number of codecs

Supported codec bitmask is populated from the payload from venus firmware.
There is a possible case when all the bits in the codec bitmask is set. In
such case, core cap for decoder is filled  and MAX_CODEC_NUM is utilized.
Now while filling the caps for encoder, it can lead to access the caps
array beyong 32 index. Hence leading to OOB write.
The fix counts the supported encoder and decoder. If the count is more than
max, then it skips accessing the caps.

commit 0768a9dd809e ("media: venus: hfi_parser: Add check to keep the
number of codecs within range").
