711: Rename FnScopes and move them below the expr module r=matklad a=flodiebold

Extracted from #693 to reduce the diff and make rebasing easier for me 😉 

The scopes belong to a body, which could be that of a function, but also a constant, static or array size. So this moves them to a submodule of `expr`.

Also move the `expr_scopes` query from `query_definitions` to that module.
