Add a description of ChromaTS into the software manual.

JVET-P0983/P0391: remove sps maximum sbt size flag: add configurable parameter to use 64 size SBT in encoder RDO

Move chroma qp offset from PPS extension to PPS

 Added back the TMVPModeId config parameter. \n m_PPSTemporalMVPEnabledIdc is now set based on both TMVPModeId and PPSorSliceMode.

 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.

Remove partitioner factory to simplify memory allocation for the
partitioner (use stack instead of heap)

fix CHECK on cu mode, considering palette mode

Correct position of new entry in table

The size of normalShiftTab[] introduced by
JVET_O0567_MVDRange_Constraint is increased such as to match the
number of imv values which is increased by JVET_O0057_ALTHPELIF

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 for the case that uninitialized or invalid best cost values are referred during search candidate selection

BugFix of encoder deblocking optimization: add initialization of m_ctuXLumaSamples and m_ctuYLumaSamples, align with 4x4 deblocking
