- LFNST signaling depending on transform skip flags
- disabling chroma LFNST for single tree
- additional scaling condition for LFNST

  - Remove additional dead code.

  - Move the following SPS syntax elements:
      sps_log2_ctu_size_minus5
      sps_idr_rpl_present_flag
      sps_bdof_pic_present_flag
      sps_smvd_enabled_flag
      sps_dmvr_pic_present_flag
      sps_isp_enabled_flag
      sps_mip_enabled_flag
      sps_sbt_enabled_flag
      sps_lfnst_enabled_flag
      sps_affine_amvr_enabled_flag
      sps_affine_prof_enabled_flag
      sps_prof_pic_present_flag
      sps_bcw_enabled_flag

  - Move the following PPS syntax elements:
      entropy_coding_sync_enabled_flag
      constant_slice_header_params

  - Add missing monochrome conditions for the following SPS syntax elements:
      qtbtt_dual_tree_intra_flag
      sps_cclm_enabled_flag

  - Add missing sps_mrl_enabled_flag and associated behavior.

  - Remove transquant_bypass_enabled_flag from PPS.

use MAX_NUM_CHANNEL_TYPE instead of MAX_NUM_COMPONENT - 1

  - Add picture header and related syntax changes.

1. enabling the encoder-side RD check of ISP mode when ACT is disabled at CU level
2. ACT intra RD code clean-up

- remove unnecessary checks, restrict Hadamard encoder search (non-normative, bit-identical for CTC)

Detail
- Fix the mis-alignment of rate and distortion during palette coding RD decision.
- Use different weights on luma component cost and chroma component cost.

Enable BDPCM for Chroma for 444.
