REGRESSION(r171593) [Mac] Media controls create a large (and unnecessary) backing store
https://bugs.webkit.org/show_bug.cgi?id=137757

Reviewed by Eric Carlson.

Source/WebCore:

In r171593, a <div> was added to the media controls which is only ever used on iOS. Instead
of creating and adding this <div> in mediaControlsApple.js (which is used on OS X), this
<div> should be created and added in mediaControlsiOS.js, which requires overloading
Controller.addControls.

* Modules/mediacontrols/mediaControlsApple.css:
(audio::-webkit-media-controls-panel.hidden): Drive-by fix: allow the panel itself to be hidden.
(video::-webkit-media-controls-panel-composited-parent): Deleted.
* Modules/mediacontrols/mediaControlsApple.js:
(Controller.prototype.createControls): Remove the composited parent.
(Controller.prototype.addControls): Ditto.
* Modules/mediacontrols/mediaControlsiOS.js:
(ControllerIOS.prototype.createControls): Create the composited parent.
(ControllerIOS.prototype.addControls): Copied from (previous) apple.js.
