Add new Transit type to pass through from split to remote animation

* Revert of ag/27904335 with additions
* For the original bug, we were consuming the transition because
we want to monitor things while split is active, but we weren't
allowing the remote animation to run even though split did not
have any animation to play.
* If we consume a transition that has a remote, keep track of it
and invoke it's start animation in StageCoordinator's startAnimation

Fixes: 353120156
Test: Original bug from revert doesn't repro, new bug
also doesn't repro. General split cases work
Flag: EXEMPT bugfix
