JVET-O1143: motion and in-loop filter low-level operations adaptation when subpic boundaries are treated as pic boundaries

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

The CCALF reconstruction function used by the encoder is separate
from the one used by the decoder. !1280 addressed issues in the
decoder. This commit addresses a similar issue in the encoder.

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.

JVET-Q0806 Geo related adoptions (JVET-Q0059, JVET-Q0077, JVET-Q0123, JVET-Q0188, JVET-Q0242_GEO, JVET-Q0309, JVET-Q0365 and JVET-Q0370)

BDPCM Chroma syntax is disallowed to signal when ACT is enabled for CU.
Decision(BF/SW): Adopt JVET-Q0353 method 1.

- compile fix for macOS
- initialize rectangular slice map before using it for subpictures

   - Fix encoder segmentation fault when checking IBC reference.
