[X86] Standardize (V)AESKEYGENASSIST instruction naming (llvm#158046)

Remove unnecessary 128 postfix

Add missing immediate to the signature (e.g. AESKEYGENASSISTrr ->
AESKEYGENASSISTrri).

Makes it easier for downstream scripts to determine the instruction name
from the assembly without overrides
