Before, functions created using the NativePDB plugin would not know about their mangled name. This showed when printing a stacktrace. There, only the function name was shown. For https://github.com/llvm/llvm-project/issues/143149, the mangled function name is required to separate different parts. This PR adds that name if available. The Clang AST nodes also take in a mangled name, which was previously unset. I don't think this unblocks anything further, because Clang can mangle the function anyway.
