Add a CTS test for SYSTEM_ALERT_WINDOW permission holding
app to be able to start activities from background
The app opp needs to be disabled for all tests (and enabled
for only that new test), since permissions are granted by default
when packages are installed in CTS.
Bug: 122578167
Test: atest BackgroundActivityLaunchTest
