Refactor virtual display creation and cleanup

* Consolidate all resources tied to display in newly added
  VirtualDisplayWrapper data class.
* Simplify virtual display creation logic but moving all
  business logic inside VirtualDeviceImpl.createVirtualDisplay
* Release all not-yet released displays when the virtual device
  is closed.
* Fix locking issues (unnecessary holding of lock, vs missing locking).
* Fix deadlock caused by lock inversion when holding mVirtualDeviceLock during calls into mInputController / InputManagerInternal.
