avcodec/cbs_lcevc: don't return an error if a Process Block is missing
padding bits
Samples made following the current (for now) faulty specification may not
include alignment bits at the end of VUI parameters, so instead of erroring
out, warn about it and keep going.
In a writing scenario, like the lcevc_metadata bsf, the output bitstream
will
be written with them.
