- Harmonize coefficient group sizes of chroma TBs to those used in luma TBs
- For 2x4/4x2 chroma TBs, retain 2x2 CG size.

includes:
- rename flag HandleCraAsBlaFlag to HandleCraAsCvsStartFlag
- changes of NAL unit types (reduced number)
- profile_tier_level and general_constraint_info structures

- remove duplicate ALF parameters from Slice
- add activation (to avoide overwriting when a new APS arrives)
- rename macro

Obsolete code relying on dead code like g_aiT64 array.

Use a single array with elements that comprise scan x position, y
position, and index into block instead of separate arrays.

Simplify array initialization code

There is a conflict with JVET_M0427_INLOOP_RESHAPER that is triggering a debug assertion that checks that the width is not 1.

Fixed transition point between GR and TU + EG(k) escape codes for coefficient coding. Use limited prefix length for escape codes.

  * Division table reduction
  * bit-width restriction

removed binary decision tree (seems to be a bit of an overkill at this stage of the project) as a preparation for the integration of M0421

code optimization of triangle weighting process

clean up useless array and its related code; resolve the merge conflict; include MDLM modes in SATD checking.
