IDLGenerators: Add a callback for when a setlike's set is modified

Browse Source 
For simplicity, this requires that the setlike Foo class has a
`void on_set_modified_from_js(Badge<Bindings::FooPrototype>)` method.

This will be called after the set is modified from a generated `add()`,
`delete()`, or `clear()` method.
