Inflate Action Views when in Menu Inflater

This adds Action View creation to the ShadowMenuInflater and allows the setting/getting of an Action View on the `TestMenuItem`.

A more long term solution to this would be to use the real `MenuInflater` to take care of this but I feel this is a good compromise until someone can sink the time into that (I think @xian might have already tried this).

Additionally, it might be good to drop some time into supporting Action Providers to be used also.
