feat(ios): remove simulator camera restriction

Remove the compile-time check that throws `notAvailableOnSimulator` error
on iOS simulators. This enables camera functionality with tools like
RocketSim that provide virtual camera support in the iOS Simulator.

Also removes the now-unused `DeviceError.notAvailableOnSimulator` case.
