Properly define va_arg and va_list for aarch64-apple-darwin
From [Apple][]: > Because of these changes, the type `va_list` is an alias for `char*`, > and not for the struct type in the generic procedure call standard. With this change `/x.py test --stage 1 src/test/ui/abi/variadic-ffi` passes. Fixes #78092 [Apple]: https://developer.apple.com/documentation/xcode/writing_arm64_code_for_apple_platforms
