Make RenderThemeIOS build on ControlStyle::State rather than
ControlStates::States. The ControlStates architecture is dated, does
not account for shadow hosts, and should probably be disappeared
entirely. This is an incremental step towards that goal.

Then provide the switch's thumb painting code has access to the system
outline color.

And ensure that by default we don't draw an outline for a switch on
iOS. Web developers can override this by using a non-auto outline-style
value, but that will not draw the outline around the thumb.
