JVET-Z0099: enabling deblocking in RDO and adjusting tc and beta offset for random access and low delay

- restore TemporalFilter parameter
- print warning when parameters are outside set that has been
  extensively tested

Also added parameters ALFAllowPredefinedFilters and CCALFStrength and note on that that refinement of quantized filter coefficients not is used.

Also fixes #738

Chroma QP mapping tables are modified such that the relationship
between luma PSNR an chroma PSNR is on average closer to the
one observed with HM 16.20.
The net effect is that bits are shifted from chroma to luma and
BD-rate differences between VTM and HM are most consistent across
components.

BD-rate between VTM 8.0 and HM 16.20:
AI: -24.09% -31.32% -32.82%
RA: -34.84% -46.33% -46.91%
LB: -30.02% -42.62% -40.94%
LP: -33.12% -44.28% -42.80%

BD-rate between VTM 8.0 plus this change and HM 16.20:
AI: -24.99% -25.35% -26.86%
RA: -35.76% -39.04% -40.03%
LB: -30.56% -32.89% -30.77%
LP: -33.62% -34.86% -32.56%

- remove picture partitioning section from CTC file (so that they can be combined wit partitioning in any order)
- remove random access parameters from partitioning examples (combines well with AI or LD too)
- add examples for three slices with slice layout inference from subpictures and without
- try to make naming somewhat consistent

Added main_10 and main_444_10 profiles, and removed old profiles.
Use 'auto' to automatically select (changed default of cfg files).
Use 'none' to produce non-conforming bitstreams.

Also added a structure that describes the features of each
profile/level/tier, should be added as further constraint checks added.

  - Remove bricks and related syntax.
  - Add new tile / slice syntax from P1004.
  - Fix cross tile / slice prediction bugs.
  - Update config files and documentation with new tile / slice config options.

same change made to encoder_lowdelay_P_vtm.cfg as done to encoder_lowdelay_vtm.cfg done in previous commit (LMCSOffset = 1), as LMCS tool off results for LDB and LDP are very similar.
