Support Intel AVX10.2 media instructions
In disassembler part, for vnni instructions, we extended previous
VEX part using %XE in disassembler to promote them to EVEX by reusing
the original VEX table. For vmpsadbw, we will also use %XE. However,
it is hard to reuse the VEX table, so we are using new ones.
In assmbler part, we put the vnni table entries with previous vnni
instructions since they are just promotion from AVX-VNNI-INT{8,16}.
Since we will prefer VEX encoding, we need to use the different table
order in template <vnni>, which prefers EVEX due to earlier introduction
for AVX512_VNNI than AVX_VNNI. This means a new <vnni>. For vdpphps
and vmpsadbw, we put them at the end of the table, with future AVX10.2
instructions.
Nit: I will remove the arch requirement for avx_vnni_int{8,16} in
evex-promote testcases after AVX10.2 implies AVX-VNNI-INT{8,16}.
