[FoldableDeviceStateProvider] Do not listen to hall sensor when not used

Disables listening to hall sensor when the new
posture based closed state flag is enabled.

When this flag is enabled we do not rely on hall
sensor and use hinge angle sensor instead.

Hall sensor is a wake-up sensor and it might
waste power by waking up CPU when not needed.

Test: manual check in sensor service dumpsys
  that we don't listen to hall sensor anymore
Test: atest BookStyleDeviceStatePolicyTest
