Improves overview split adjacent launch animation

* Translation gets scaled along with the parent,
so the secondary thumbnailView which has a translate on
it gets exaggerated as the parent goes to fullscreen
scale.
* Now we inversely scale translationX/Y properties,
however it seems like the interpolation is still slighly
off at the beginning of the animation (or maybe some other
value, such as pivot, etc)

Bug: 260814999
Test: Manually slowed down animation and observed
