Merge branch 'N0280-ResidualCodingTransformSkip' of https://vcgit.hhi.fraunhofer.de/nguyen/VVCSoftware_VTM into N0280-ResidualCodingTransformSkip

#define JVET_N0127_MMVD_SPS_FLAG                          1

Implicitly infer the number of MMVD base merge candidate to be 1 as MaxNumMergeCand being equal to 1, and mmvd_merge_flag is not signalled in this case.

- tiles are in the VVC spec for 3 meeting cycles now
- cleanup helps with adaptation for tiles to current draft

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

This is for the case where JVET_M0464_UNI_MTS is disabled

Code was salvaged from !306

AMVR (formely IMV) now has only one mode, which used to be mode #2
- remove SPS imv_mode parameter
- remove encoder configuration for mode #1 (mode #2 replaces mode #1)
- adapt config files to refer tp mode #1
- rename SPS syntax elements and access functions to AMVR

Note: IMV to AMVR renaming in other parts of the software should be done by proponents.

- The M0297 zero-out is also supported for SBT now.
- The zero-out scanning code is moved out of residual_coding_subblock.

Fix of the DQP signaling when there are multiple luma TUs in Single Tree and there is only one TU containing all of the chroma information

- all elements of SPSNext are moved into SPS
- syntax elements of SPS are sorted according to draft (as far as possible)
- comments were added where software and draft diverge

Remove unused contexts and split intra mode contexts into luma and
chroma sets to align with text description
