Fixing Rotation Bug for BiometricCredMan

This fixes the rotation bug for credential manager by creating a
[BiometricFlowState] object. This object is used throughout the flow to
ensure that on re-compose, the state does not violate any constraints.
Namely, if a rotation or other similar configuration change happens that
causes a recompose, the Ui has consistent state.
