Mismatch with vtm on lfnst_idx parsing

Reported by: forayr Owned by:

Description

lfnst_idx is not parsed in vtm when transform_skip_flag == 1.
To align the behaviour, the spec should be modified such as:

    if(Min(lfnstWidth, lfnstHeight) >= 4 && sps_lfnst_enabled_flag == 1 &&
+      transform_skip_flag[x0][y0][0] == 0 &&
       CuPredMode[chType][x0][y0] == MODE_INTRA &&
       (!intra_mip_flag[x0][y0] || Min(lfnstWidth, lfnstHeight) >= 16) &&
       max(cbWidth, cbHeight) <= MaxTbSizeY)

    {
      if((IntraSubPartitionsSplitType != ISP_NO_SPLIT || LfnstDcOnly == 0) &&
         LfnstZeroOutSigCoeffFlag == 1)
      {
        lfnst_idx
      }
    }
