Add a description of ChromaTS into the software manual.

 Added back sps_temporal_mvp_enabled_flag to align with specification text in JVET-O2001-vE. \n This also means that sps_sbtmvp_enabled_flag can be signaled in SPS as before instead of in PPS.

Use roundTransPrecInternal2Amvr() instead of
roundIbcPrecInternal2Amvr() since half-pel precision is not
supported by the latter

fix compilation errors by code merging and harmonize with JVET_O0119_BASE_PALETTE_444, JVET_O0502_ISP_CLEANUP, JVET_O0472_LFNST_SIGNALLING_LAST_SCAN_POS, JVET_O0545_MAX_TB_SIGNALLING

fix some JCCR related indentation, encapsulation, and descriptive text, add --PYUV to software manual
