lavc/vvc: Use second definition of MinQtLog2SizeIntraC if relevant MinQtLog2SizeIntraC is usually (eq. (51) from VVCv3) defined as sps_log2_diff_min_qt_min_cb_intra_slice_chroma + MinCbLog2SizeY However, in the case ph_log2_diff_min_qt_min_cb_intra_slice_chroma is present, it is instead (eq. (83) from VVCv3) defined as ph_log2_diff_min_qt_min_cb_intra_slice_chroma + MinCbLog2SizeY When ph_log2_diff_max_bt_min_qt_intra_slice_chroma and ph_log2_diff_max_tt_min_qt_intra_slice_chroma are present, so is ph_log2_diff_min_qt_min_cb_intra_slice_chroma, and so we should use the second definition of MinQtLog2SizeIntraC, rather than the first, when calculating the bounds for these syntax elements.
