JVET-X0071: Improvement of in-loop filters: Chroma bilateral filter, band-based ALF classifier and longer filter for CCALF

In ECM, xSubPuBio would be called during MC only when BASE_NORMATIVE=0 (which implies BDOF_RM_CONSTRAINTS=0).
It requires accessing spanned motion field to get MVs for BDOF operations.
However, encoder does not span TM-refined motion before MC performs while decoder does, triggering mismatching between encoder and decoder.
This mismatching issue can be reproduced by "-c ./tool-on/encoder_randomaccess_vtm.cfg -c BQSquare.cfg --SEIDecodedPictureHash=1 -ip 64 -q 27 -ts 1 -f 65 -fs 64"

Fix macro issue to avoid encoder crash when disable IF_12TAP_SIMD,
SIMD_4x4_12 is relying on IF_12TAP_SIMD so that when IF_12TAP_SIMD is turned off, SIMD_4x4_12 should be off automatically.
