Close Views media galleries and captive portal window proxy dialogs on interstitial WebUI

Configure Views media galleries and captive portal window proxy dialogs
to be closed when interstitial WebUI is displayed (e.g. for SSL warnings
prior to page load).

This is effectively a no-op for these dialogs, but is desirable so that
all web contents modal dialogs have consistently configured behavior;
the underlying WebContents is controlled by the application and Chrome
OS respectively, so should not produce interstitial WebUI.
