rust: Warn if non-staticlib/cdylib Rust libraries are linked into targets of other languages

[sdroege]

Only staticlib/cdylib crate types have a useful ABI that can be consumed by other languages and linking other crate types into a target of some other language is almost certainly a mistake.

Related also #11721 . There rlibs are linked into a C++ binary, but that shouldn't happen at all in that case and is a bug in itself.
