Restrict the space bubbles are centered in while in landscape
In landscape don't use the full screen width, instead, restrict to a
percentage of the screen & enforce a minimum of the width of the screen.
* Updates the displaySize passed to ExpandedAnimationController
to be the "real size", this is consistent with what BubbleExpandedView
uses now
* Alters positioning calculations in ExpandedAnimationController &
accounts for notches / screen decorations
Test: manual - have multiple bubbles
- expand the stack
- rotate the device
=> observe that the bubbles look nicely centered (i.e. not
too much space or too little space) in landscape & portrait
