[2/n] Display stack provides DisplayInfos

For all possible states a device can assume, the DisplayManagerService
provides the DisplayInfo associated with that layout of the logical
display. WindowManager applies each possible rotation to these
DisplayInfo. This, in turn, is used to calculate the possible max
WindowMetrics on the device.

Done:
* Display stack builds collection of DisplayInfo, for all
 possible display states (folded, unfolded on jumbo)
* Display stack pushing set of DisplayInfos to WindowManager
* WindowManager calculates max bounds for all possible
  (display layouts x rotations)

Not started:
* WindowManager calculates insets for each rotation
