  [RISCV] Support LLVM IR intrinsics for XAndesVDot (#140223)

This patch adds LLVM IR intrinsic support for XAndesVDot similiar to
#139860.

The document for the intrinsics can be found at:

https://github.com/andestech/andes-vector-intrinsic-doc/blob/ast-v5_4_0-release-v5/auto-generated/andes-v5/intrinsic_funcs.adoc#andes-vector-dot-product-extensionxandesvdot
and with policy variants
https://github.com/andestech/andes-vector-intrinsic-doc/blob/ast-v5_4_0-release-v5/auto-generated/andes-v5/policy_funcs/intrinsic_funcs.adoc#andes-vector-dot-product-extensionxandesvdot

The clang part will be added in a later patch.
