Use display context to inflate navbar on external display

- Disable rotation suggestion button if the navbar is on
  non-default display because there is no accelerometer sensor.
- Avoid leakage by removing navbar fragment from fragment
  host when display is removed.

Bug: 117746225
Bug: 117744614
Test: atest SystemUITests
Test: manual - create a virtual display with system decoration.
      The navbar on the virtual display should not change when
      rotating or changing density of default display.
      And after releasing the display, use command "dumpsys
      activity service com.android.systemui/.SystemUIService |
      grep NavigationBarFragment" to check the number of instances.
