fix CHECK on cu mode, considering palette mode

With the decision "Adopt to mandate the presence of AU delimiter
for each AU", AUDs are enabled by default and a warning is printed, if
they are disabled. The config parameter should be removed later and the
decoder needs to check for AUD presence.

SIMD code rewritten to run 2x faster

- Hash ME
- Rate Control
- LMCS

Clean up virtual boundary related checks:
- Replace modulo operation by bitwise AND
- Define local variable instead of having same computation appear
  dozens of times in code
- Use const type qualifiter where appropriate

following condition is added to fix the bug.
"affMrgType.GBiIdx[affMrgType.numValidMergeCand] = (dir == 3) ? gbiIdx : GBI_DEFAULT;"

Add compliance checks for:
sps_log2_diff_max_bt_min_qt_intra_slice_luma
sps_log2_diff_max_tt_min_qt_intra_slice_luma
sps_log2_diff_max_bt_min_qt_inter_slice
sps_log2_diff_max_tt_min_qt_inter_slice

The sanitizer reports that a call to getBrickIdxBsMap() tries
to access an out-of-bounds element. The size of the array
brickIdxBsMap[] is thus increased by 1 and its last element is
initialized to some large value

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

Correct position of new entry in table

Read 32 bits instead of 64 bits for blocks of width 2 such as to
not read past array boundaries

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

There is no scaling matrix for palette prediction

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

- only cu_qp_delta is conditioned by (CbWidth > 64 || CbHeight > 64)
- move parsing of tu_joint_cbcr_residual_flag[] between cu_chroma_qp_offset_idx and transform_skip_flag instead of before cu_qp_delta
