Revert D121984 "[RISCV][NFC] Moving RVV intrinsic type related util to llvm/Support"

This reverts commit ad57e10d and 1967fd8d

llvm/lib/Support/RISCVVIntrinsicUtils.cpp introduced llvm/TableGen includes,
a circular dependency https://llvm.org/docs/CodingStandards.html#library-layering
I think this particular instance is serious and should be reverted.
