  [msan] Add Instrumentation for Avx512 Instructions: pmaddw, pmaddubs (#153919)

This applies the pmadd handler (recently improved in https://github.com/llvm/llvm-project/pull/153353) to the Avx512
equivalent of the pmaddw and pmaddubs intrinsics:
  <16 x i32> @llvm.x86.avx512.pmaddw.d.512(<32 x i16>, <32 x i16>)
  <32 x i16> @llvm.x86.avx512.pmaddubs.w.512(<64 x i8>, <64 x i8>)
