use MAX_NUM_CHANNEL_TYPE instead of MAX_NUM_COMPONENT - 1

Signalling of CPB timing parameters for sub-layers in DU-based HRD
operations
Remove pt_max_sub_layers_minus1 and use corresponding syntax element in
BP SEI
Make parsing of BP, PT and DUI SEI independent from SPS

Constraint that vps_video_parameter_set_id shall be greater than 0
Added that the bitstream does not contain any VPS when
signalled sps_video_parameter_set_id is equal to zero
(was already in VVC Draft, but not in VTM)

  - Add picture header and related syntax changes.

Generate prefix APS instead of suffix

Align the encoder side output reporting conditions for RPR scaling factors with those of the decoder.

Removal of pps_temporal_mvp_enabled_idc and constraint that
slice_temporal_mvp_enabled_flag has to be equal to 0 if there are no
reference pictures with the same resolution as the current picture

JVET-N0867: Added check to confirm that the GOP size and picture order fullfils the configured DetlaTimes. If not DeltaTimes in BP and picture Timing are not used.

Will slightly impact CTCs, especially at low QPs.

 The following fixes has been made:

   - Removed prefixes like 'i' for new variables

   - Adding braces also for if-clauses with a single statement

   - Removed some trailing spaces

   - Changed variable precedingDRAP in Picture from int to bool

When calling pcPicCurr->finalInit() pointers to LMCS APS or Scalining List APS
can be zero. Dereferencing those is undefined. It's also not necessary, because
the arguments passed as reference are later converted to pointers again.

 Implementation of the Dependent RAP indication SEI message. Pictures are marked as DRAP pictures using the encoder config parameter DRAPPeriod, which sets DRAP pictures periodically. Conformance checks are performed at the decoder side to verify that the DRAP pictures follow the constraints in the VVC specification.
