"use" unsupported

[guybedford]

Currently even without external wit file support, use against self-interfaces is also not working, eg for the world:

interface types {
  record app-props {
    name: string,
    count: u32
  }
}

default world app {
  use self.types.{app-props}
  export render: func(props: app-props) -> string
}

Fixing this will involve upstreaming the bindings inversion into the transpiler bindgen in jco, now that the technique is proven.
