[Swiftify][StrictMemorySafety] Test `unsafe` warnings in wrappers (NFC) As _SwiftifyImport now emits the `unsafe` keyword to prevent warnings about unsafe code in the macro expansions, we should make sure that our tests do not emit any warnings. It turns out that calls to RawSpan::withUnsafeRawPointer are not recognised as unsafe, so we sometimes get warnings about using `unsafe` on a safe expression. This issue is tracked under rdar://145899513.
