Whether to override the screen reader status given by the operating system.
Set this property if you need to override the value returned by
AssistiveSupport.isScreenReaderEnabled.
If this property is set to AssistiveSupport.ScreenReaderStatusOverride.OSDriven, its default
value, AssistiveSupport.isScreenReaderEnabled returns the actual screen reader status given by
the operating system. Otherwise, this property forces AssistiveSupport.isScreenReaderEnabled
to return a specific value, regardless of the status given by the operating system.
Note: This property does not affect the actual status of the screen reader on the user's device.
