Add Display#FLAG_ALLOWS_CONTENT_MODE_SWITCH 

- For local display device and wifi display device, the flag should be
  enabled by default.

- For overlay display device used in CTS, the flag should be disabled
  by default; for other overlay display devices, the flag should be
  enabled by default to simulate connected displays.

- Virtual display device should not set this flag at this point.
