  1. 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 rust-lang#78092
