Add the support for AMD EPYC zen 5 processors(EPYC-Turin).
Add the following new feature bits on top of the feature bits from
the previous generation EPYC models.
movdiri : Move Doubleword as Direct Store Instruction
movdir64b : Move 64 Bytes as Direct Store Instruction
avx512-vp2intersect: AVX512 Vector Pair Intersection to a Pair
of Mask Register
avx-vnni : AVX VNNI Instruction
