lavc/vvc: Stricter bound on pps_exp_slice_height_in_ctus_minus1

When pps_num_exp_slices_in_tile[i] is nonzero, the ith tile is made up
of pps_num_exp_slices_in_tile[i] slices stacked atop one another, where
the height of the jth slice in the ith tile is given by
pps_exp_slice_height_in_ctus_minus1[i][j].  The sum of the heights of
the slices in the tile should not exceed the height of the tile itself.
