Port CONFIG_NEW_INTER_MODES to research branch

AV1 has symbols NEARESTMV and NEARMV to differentiate
between MV0 (nearest) and MV1/MV2/MV3 (near). This
distinction was inherited from VP9, which only had two
motion vectors and only used two symbols. This change
cleans up the syntax so a single mode, NEARMV, can be
used to identify any motion vector. This change is
extended to cover the compound modes. Moreover, the
NEWMV mode, which could only access 0, 1, 2, is
extended and can access any motion vector.
