Log.wtf WM timeouts only after 5s

This CL splits the current launch timeout in ActivityLaunchAnimator so
that we simply warn for timeouts after 1s but Log.wtf if the remote
animation is not started or cancelled within 5s.

Bug: 306956311
Test: Manual. ActivityLaunchAnimatorTest explicitly disables timeouts
 and making this code testable would be a much bigger change.
