Add custom message dialog for Respond via Message.

We don't want to require SMS applications to implement activities that show
over lock just to handle the "respond via custom message" scenario for
rejecting phone calls. This change adds an entry dialog into the phone call
UI. A separate change removes the code in the Telephony service that would
have asked the default SMS app to show UI.
