"DO NOT MERGE" Adapt tests for display cutout

With display cutout some rotations will not cause config changes
in certain scenarios because of different window insets.
This CL changes the fixed orientation test to acknowledge the cutout
and disables other config change tests where the outcome is hard to
predict.

Test: ActivityManagerAppConfigurationTests#testFixedOrientationWhenRotating
Test: ActivityManagerConfigChangeTests
