LOG: [X86] Standardize (V)AESKEYGENASSIST instruction naming (#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

Added: 
    

Modified: 
    llvm/lib/Target/X86/X86InstrSSE.td
    llvm/test/TableGen/x86-fold-tables.inc
    llvm/test/TableGen/x86-instr-mapping.inc

Removed:
