Use Diplay.getMetrics in DisplayController

- This is a workaround of b/163815566, where DisplayMetrics is stale
  when onDisplayChanged is called.
- Instead of relying on stale DisplayConext, get the DisplayMetrics
  from the Display directly.
- Also optimized how DisplayController.Info is created by passing in
  Display only
- Use mDisplayContext.getDisplay directly if availalbe

Bug: 163815566, 160544577
