Support Intel AVX10.2 BF16 instructions
In this patch, we will support AVX10.2 BF16 instructions. All of them
are new instructions forms. In current documentation, it is still
VSCALEFPBF16, but it will change to VSCALEFNEPBF16 eventually.
In disassembler part, we added %XB to reduce W table pass since all
of them get evex.w=0.
