Improve outgoing call UI responsiveness

* Start InCallUI immediately once Telecom binds

* This CL is a bandaid for improving outgoing call responsiveness
in the MR1 timeframe. Refactoring InCallActivity into dynamically
added fragments and modifying its lifecycle with respect to
the call list is too risky.

* Add a lightweight activity (CircularRevealAnimationActivity)
that is used to display the circular reveal animation while
the significantly heavier InCallActivity is starting up

* Inside InCallServiceImpl.bind, start the reveal animation once
bind is called to avoid being blocked by any synchronous work in
Telecom.

* Refactor CallCardFragment.animateForNewOutgoingCall to
conditionally display the reveal animation, depending on
whether or not it was already displayed by the
CircularRevealAnimationActivity.

* Refactor the calculation of theme colors in InCallPresenter so that
the CircularRevealAnimationActivity can use those colors as well.

* Remove PENDING_OUTGOING from the list of call states that bring up
InCallUI.
