In ECM, xSubPuBio would be called during MC only when BASE_NORMATIVE=0 (which implies BDOF_RM_CONSTRAINTS=0).
It requires accessing spanned motion field to get MVs for BDOF operations.
However, encoder does not span TM-refined motion before MC performs while decoder does, triggering mismatching between encoder and decoder.
This mismatching issue can be reproduced by "-c ./tool-on/encoder_randomaccess_vtm.cfg -c BQSquare.cfg --SEIDecodedPictureHash=1 -ip 64 -q 27 -ts 1 -f 65 -fs 64"

- Integration of the adopted config. (Test 4.6)
- (LFNST8, LFNST16) = (32x64, 32x96)

JVET-S0100 Aspect 3: constraints on vps_dpb_max_tid and vps_hrd_max_tid depending on vps_ptl_max_tid

Merge

During integration of JVET-R0324, mvd_l1_zero_flag was moved down
in the syntax table (see JVET-R2001-v2). This change had not been
reflected in the !1563.

These changes should not affect any bitstream

gci_no_rectangular_slice_constraint_flag,
gci_one_slice_per_subpic_constraint_flag,
gci_no_subpic_info_constraint_flag and remove
gci_one_subpic_per_pic_constraint_flag
