fix: apply collision disambiguation to guest codegen

Apply the same import_member_names() collision detection to guest.rs
that was already applied to host.rs and rtypes.rs. Without this,
guest_bindgen! would generate duplicate type aliases and getter
functions when two packages export interfaces with the same name.
