Users should be able to retrieve the code span of SMIR items.

how should we expose it. If we expose it directly (have PathBuf, line/col info and expansion info directly in the smir::Span struct), that may get expensive. If we expose it indirectly, we can do it like .kind() on smir::Ty, computing it only when requested and otherwise just storing an index.

We should encapsulate the path, so no one relies on having direct access to them. We probably want to intern the pathbuf for the file, so we don't keep replicating it.

Should we return rustc_span::Span or stable_mir::Span, agree with oli here exposing indirectly will suffice for most needs.

Add function that returns span of an item in smir

Addressees rust-lang/project-stable-mir#31

Maybe we should change `Span = Opaque` into something else, and then return `String` with newly added function, I don't think it matters that much though, since we are not storing `Span` anywhere.

Right now the spans are opaque and thus not very useful. We should add a way to retrieve file, line, col and expansion information.
