    Add name resolution to generic argument associated item bindings
    
    When specifying generic arguments to Traits we can also specify the
    associated types using `<BindingName=i32>` syntax we need to add
    name resolution to the type argument here and rely on the type
    resolution pass to ensure the associated type exists and to setup the
    associated types accordingly.
    
    Addresses #1720
