Add a new abstract class MagnificationFeaturePreferenceController that extends TogglePreferenceController, to wrap inSetupWizard setter/getter. Then for magnification feature preference controllers like alwaysOn or followTyping, they can just check isInSetupWizard to decide whether hiding in setup wizard. Besides, in ToggleScreenMagnificationPreferenceFragment we cache a flag mInSetupWizard when fragment created, so we can pass the info to the preferece controllers when creating them.
