Matthias Krüger b9c6b337ce Rollup merge of #141341 - folkertdev:limit-VaArgSafe-impls, r=workingjubilee 
limit impls of `VaArgSafe` to just types that are actually safe

tracking issue: https://github.com/rust-lang/rust/issues/44930

Retrieving 8- or 16-bit integer arguments from a `VaList` is not safe, because such types are subject to upcasting. See https://github.com/rust-lang/rust/issues/61275#issuecomment-2193942535 for more detail.

This PR also makes the instances of `VaArgSafe` visible in the documentation, and uses a private sealed trait to make sure users cannot create additional impls of `VaArgSafe`, which would almost certainly cause UB.
