SF: Deduplicate mock scheduler setup in tests
Extract TestableSurfaceFlinger::setupMockScheduler, and add an option to
customize the PhysicalDisplayId of the injected RefreshRateSelector (and
its display modes), so that tests can later inject a DisplayDevice with
a matching ID. Remove the DisplayModesVariant with two display modes, as
the few tests that used it are unrelated to scheduling and will later be
decoupled entirely.
