Fix part of dual shade insets flicker when window moves to a different display
When the shade moves to a different display there is a 3 frames flicker where the shade header jumps around.
This cl addresses the first frame flicker, that had wrong shade header position as the displayCutout and cornerRadius StateFlows were being re-created at every root view recomposition with the wrong initial values.
With this cl:
- The flows are created once, outside the composable
- corner radius is updated every time the shade moves to a different display (e.g. external displays normally don't have any corner radius, and this was triggering a wrong offset)
The remaining 2 frame flickers will be addressed in a follow up.
