JVET-O0265/JVET-O0629/JVET-O0418/JVET-O0329/JVET-O0378/JVET-O0411/JVET-O0279:Simplified motion field storage for TPM

It cleans up old ISP code that is no longer used anymore. The code was used to allow only one ISP split depending on the block size. However, this functionality is not needed anymore after the adoption of JVET-N0308 during the Geneva Meeting in March, which limited the usage of ISP to CUs with a maximum size of 64x64 samples. This clean-up eliminates various unnecessary checks and improves the readability of the code.

Macro: JVET_O0366_AFFINE_BCW

JVET-O0219: LFNST transform set selection for a CCLM coded block. Remove duplicate code. Fix a bug due to convert MIP mode to convensional mode

JVET_O0078_SINGLE_HMVPLUT: Single HMVP table for all CUs inside the shared merge list region for IBC

JVET-O0219: LFNST transform set selection for a CCLM coded block. Remove duplicate code. Fix a bug due to convert MIP mode to convensional mode

  - Fix uses of cs->slice in post-decode steps (loop filtering, sao, dmvr set refined motion field)

  - Add isSameSliceAndTile check for top CTU QP prediction.

  - neighGbi array not properly initialized.

implements:
- splitting tiles into bricks
- raster-scan tiles
- uniform and non-uniform splits
- all tiles/bricks in one slice
- each brick one slice
- PPS syntax

missing:
- rectangular tiles
- slice header syntax

further todo:
- rework slice mode 2 to use multiple tiles for byte size matching
- lots of renaming (tile->brick)

- Previous name: Reduced Secondary Transform (RST)
- The parameter, LFNST, should be added in cfg file for enabing LFNST, i.e. LFNST = 1

- getTrTypes function is moved to TrQuant class
