Per VVCv3 p. 157, the collocated reference picture used in temporal motion vector prediction must have RprConstraintsActiveFlag equal to zero and the same CTU size as the current picture. Add these checks, fixing crashes decoding some fuzzed bitstreams. Additionally, only set up the collocated reference picture if it is actually going to be used (i.e. if ph_temporal_mvp_enabled_flag is 1), else legal RPR bitstreams will fail the new checks.
