  [RISCV] Implement intrinsics for XCVbitmanip extension in CV32E40P (#74993)

Implement XCVbitmanip intrinsics for CV32E40P according to the
specification.

This commit is part of a patch-set to upstream the vendor specific
extensions of CV32E40P that need LLVM intrinsics to implement Clang
builtins.
