wit-encoder: `use` statements are ignored in `WorldItem::InlineInterfaceExport`.

[ouillie]

I have a test to illustrate this. At trunk, when you run the test, you get this:

Diff < left / right > :
 package foo:bar;
 
 world the-world {
   export the-interface: interface {
>    use types.{ the-type as the-import };
     the-function: func(the-parameter: the-import);
   }
 }
 
 interface types {
   record the-type {  }
 }

Indicating that the statement inline_interface.use_type("types", "the-type", Some(Ident::from("the-import"))) on line 31 is effectively being ignored.

Drafting up a fix.
