Consistently use 16-bit integers to hold CC-ALF coefficients to
avoid type conversions

   - Move wrap around offset from SPS to PPS.

JVET-R0277 items 1 and 2: Modified condition for the number of active entries override flag, inference for slice_collocated_from_l0_flag

Assign correct default values (1) to collocated chroma flags in
SPS. Note that default values are used only for non-420 chroma formats.
Modify and clean up CCLM code to not unnecessarily rely on collocated
chroma flags for non-420 chroma formats.

Check that the slice signalling order is the same as the slice coding
order in case of subpictures

JVET-R0483 Comb 4: R0049 + R0271, only R0049 method 3 aspect (Skip signaling sh_ts_residual_coding_disabled_flag when sps_transform_skip_enabled_flag = 0, also proposed in R0068, R0097, R0142, R0153) as R0271 has its own macro
