Detail
- Use correct precision of distortion based on input bit-depth during the derivation of the palette for lossless coding.
- Remove the unnecessary calculation of distortion during palette coding RD decision on lossless.

Detail
- Change EG3 to EG5 in palette escape coding.

Slice-level switch between TS residual coding and regular residual coding for lossless coding as in JVET-Q0089.
One SPS flag that controls both luma and chroma BDPCM simultaneously as under JVET-Q0089 (meeting notes) - removed chroma BDPCM flag.
Modified the .cfg files to reflect high-level chroma BDPCM changes.
Fix: Disabled CCALF in lossless.cfg (necessary) CCALF cannot be used if ALF is disabled (disabled in lossless.cfg)

Sets CTC screen content config to use chroma BDPCM as in JVET-Q0785
Aligns Intra Prediction mode with BDPCM mode for chroma as in JVET-Q0110
Adds separate chroma contexts for BDPCM as in JVET-Q0110
Aligns signaling order for chroma BDPCM to match with Spec as in JVET-Q0351 and JVET-Q0785

JVET-Q0503: encoder only improvement (4 items) of palette mode
JVET-Q0712: fix palette encoder issue at high QPs. Fix on top of the optimized table in JVET-Q0503.

fix the interaction between JVET_Q0784_LFNST_COMBINATION and JVET_Q0820_ACT/JVET_Q0695_CHROMA_TS_JCCR
