Cutout: Add developer setting to mask the display cutout

Adds an option to mask the cutout by effectively shrinking the logical display
such that developers can test apps as if the device did not have a notch.

Bug: 112876936
Test: Go to Settings > Developer Options > Simulate display with cutout > "No cutout". Cutout should be hidden. Rotate screen, take screenshots, screenrecord, screen off animation should all work as expected.
