Rollup merge of #126927 - workingjubilee:vaargsafe-is-unsafe, r=joboet
core: VaArgSafe is an unsafe trait `T: VaArgSafe` is relied on for soundness. Safe impls promise nothing. Therefore this must be an unsafe trait. Slightly pedantic, as only core can impl this, but we *could* choose to unseal the trait. That would allow soundly (but unsafely) implementing this for e.g. a `#[repr(C)] struct` that should be passable by varargs. Relates to https://github.com/rust-lang/rust/issues/44930
