avcodec/cbs_av1: add a range check to tg_end
Section 6.10.1 of the AV1 spec states:
It is a requirement of bitstream conformance that the value of tg_start is
equal to the value of TileNum at the point that tile_group_obu is invoked.
It is a requirement of bitstream conformance that the value of tg_end is
greater than or equal to tg_start.
