[STL] Increase default transitionInterceptionThreshold to 0.05

In SceneTransitionLayout, the transitionInterceptionThreshold value is
used during a transition to decide whether the new gesture should
control the transition or the element in the scene. The default value is
 currently 0, which means that the animation does not need to be 100%
 complete before the gesture can control the transition in the STL.

This CL sets the tolerance value to 0.05 (5% tolerance), which means
that the gesture will control the elements of the scene when the
animation is 95% complete. This is because many animations slow down as
they approach completion and may appear finished even when they have not
 reached 100%.
