JVET-N0449: Simplification on MMVD distance table

See merge request jvet/VVCSoftware_VTM!414

MMVD simplification by removing the two largest distance entries in the
MMVD distance table using encoder only change method.
To make the number of MMVD distance entries configurable by the
software, additionally adding 'MmvdDisNum' as a new option in the cfg files.

add encoder config constraint for WrapAroundOffset to be a multiple of the minimum CU size
