Reviewed by Aditya Keerthi.

Reuse the boilerplate zooming code from other controls for the switch
control so it works correctly when zoomed using "Zoom In".

In SwitchTrackMac this scales both the inflatedTrackRect and the
trackRect as the latter is used for drawing the focus ring.

In SwitchThumbMac this adds a CGContextStateSaver for the
trackBuffer context for consistency with SwitchTrackMac. It isn't
required to address this bug. It also renames a variable for internal
consistency.
