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

Two changes are included: (1) disable fractional MVD for UHD sequences (M0312 & M0255) (2) encoder optimization for MMVD

Missing clipping for MV storage in affine

Move the gtr2 flag (the abs_level_gt3_flag in text) after the par_level_flag in the first coding pass

Adding support for chroma sample location type 2 in CCLM

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
