Auto merge of #445 - CYBAI:reexport-intohandle, r=asajeffrey

Re-export IntoHandle

When implementing `rejectionhandled` event, we'll need to add consumed rejection in task and we'll need to convert `HandleObject` into `RawHandleObject` which is `js::jsapi::HandleObject`. With exporting this trait, we can leverage the power of `into_handle` to do the conversion instead of writing a new method to get the `RawHandleObject`.
