Fix UI overlap when rotating in split select mode

Fixes an issue where you could trigger a UI overlap by rotating the phone during split select. The issue occurred because devices with insets were calling TaskView#resetViewTransforms during rotation, and not accounting for the fact that an extra transform was applied for split staging.

Fixes: 220998096
Test: Manual test on inset and non-inset devices
