cbs_av1: Reject thirty-two zero bits in uvlc code

The spec allows at least thirty-two zero bits followed by a one to mean
2^32-1, with no constraint on the number of zeroes.  The libaom
reference decoder does not match this, instead reading thirty-two zeroes
but not the following one to mean 2^32-1.  These two interpretations are
incompatible and other implementations may follow one or the other.
Therefore reject thirty-two zeroes because the intended behaviour is not
clear.
