Disable navigation bar and quick settings for Chile

From SAE 4.0 section Interruptions:
When device receive the SAE message, the pop-up must still
in screen together sound and vibration until user decide stop it.
The only way to stop the pop-up, sound, and vibration (at same time)
is the option available into pop-up, I mean “Ver” or “Siguiente”,
any other option is not allowed, as home key, power button,
volume button, etc. Thus disable navigation bar and quick settings.
Note this is done through reflection and there is no guarantee the
existence or proper function of statusBarManager APIs.

Bug: 205157514
Test: Manual test on Chilean SIM card
Change-Id: I5f5af5b9368005a80d355ab2713d4fe71b3ea53b
