Improve outgoing call UI responsiveness

* Send call extras in a bundle to the service when binding. This
provides information about the call so that the incall-service can
setup its UI immediately before the rest of Telecom is done.

* Move outgoing call flow to always go through the CallReceiver.
This allows CallActivity to finish and not block ActivityManager by
remaining as the foreground activity.
