A version the control key modifiers that is based upon the pre-Java 9 {@link InputEvent}
usage.  This mask is here for those clients that cannot be upgraded, such as those with
dependencies on 3rd-party libraries that still use the old mask style.

@deprecated use instead {@link #CONTROL_KEY_MODIFIER_MASK}
