Only allow one turnScreenOn per app resume.

The current behavior will turn the screen on if a relayout is
called. This is problematic because if the screen is off but the
client is still requesting relayouts, the relayout will trigger
a request to turn the screen on. This change ensures that the screen
will only get turned on at most once per resume. If the activity
is relaunched again, the screen can be turned on again.

Test: Set the phone to have always on ambient display. Launched the
dialer app and turned the screen off. The screen no longer turns back
on automatically.
