[APX_EGPR] Handle legacy insns that only support GPR16 (4/5)

[APX_EGPR] Handle legacy insns that only support GPR16 (4/5)

The APX enabled hardware should also be AVX10 enabled, thus for map2/3 insns
with evex counterpart, we assume auto promotion to EGPR under APX_F if the
insn uses GPR32. So for below insns, we disabled EGPR usage for their sse
mnenomics, while allowing egpr generation of their v prefixed mnemonics.

insn list:
1. pabsb/pabsw/pabsd
2. pextrb/pextrw/pextrd/pextrq
3. pinsrb/pinsrd/pinsrq
4. pshufb
5. extractps/insertps
6. pmaddubsw
7. pmulhrsw
8. packusdw
9. palignr
10. movntdqa
11. mpsadbw
12. pmuldq/pmulld
13. pmaxsb/pmaxsd, pminsb/pminsd
    pmaxud/pmaxuw, pminud/pminuw
14. (pmovsxbw/pmovsxbd/pmovsxbq,
     pmovsxwd/pmovsxwq, pmovsxdq
     pmovzxbw/pmovzxbd/pmovzxbq,
     pmovzxwd/pmovzxwq, pmovzxdq)
15. aesdec/aesdeclast, aesenc/aesenclast
16. pclmulqdq
17. gf2p8affineqb/gf2p8affineinvqb/gf2p8mulb
