When we stop scheduling for new frames on RenderThread, we should
put the running animations on pause, rather than purge the list
of the running animations, such that in the next full
sync, the animations that were paused will continue to run.

This CL changes the target of VD specific animators to VectorDrawable,
instead of RenderNode. The benefit of doing so is that animators can
now detect whether the animation is meaningful by checking whether
their VD target is in the display list. If not, that means the VD is
not drawing for the current frame, in which case we can be smarter
and more power efficient by removing the animator from the list and
posting a delayed onFinished listener callback.
By setting VD as the animation target, when an ImageView decides to
update its drawable from one AVD to something else, we'll be able
to detect that the previous AVD is no longer in the display list,
and stop providing animation pulse to the stale AVD, which is
something we couldn't do previously. This change also
handles the case where one AVD instance could be drawn in two
different views.

Bug: 17372309
AnimationContext::startFrame() happens both with and without
the UI thread lock. Pass the TraversalMode into it so
that ThreadedRenderer's subclass can correctly decide
when it is safe to push over mPendingAnimatingRenderNodes, as doing
so outside of the lock is Very Bad.

Bug: 17372309
Fixes a case where UI thread and RT thread both used the same method
which wasn't safe for either of them.
Adds additional assertions & logging in unusual circumstances to
try and track down where the issue is occuring from.
