Implement the check when NNPFA activates a non-base filter, there shall be corresponding NNPFC (i.e., with the same ID and same base flag) already present.

JVET-AE0142 item 3 and item 4: Fix two bugs including an added condition and a nnpfc_purpose related constraint.

Also addresses #1608

Define JVET_AE0057_MTT_ET is placed at the appropriate location in Typedef.h
The Luma channel test condition is updated EncCu.cpp
The threshold value lower range is clipped to 0 instead of allowing it to take negative values.
JVET document number information is removed

The proposal JVET-AE0057 is implemented under the define JVET_AE0057_MTT_ET in VTM software. A config file parameter (MTTSkipping) is also added to turn on or off the MTT early termination. The 64x64 luma CU no-split intra RD cost is compared against a threshold to decide whether to evaluate MTT splitting for current 64x64 luma CU.

JVET_AE0060_COND_SIG_INF: Signal nnpfc_chroma_loc_info_present_flag only when nnpfc_out_order_idc is not equal to 0 and infer nnpfc_chroma_loc_info_present_flag to be equal to 0 when not present.
