Reviewed by Tim Horton.

We counter scale <audio> controls on iOS, which causes them to
escape their element bounds if the user zooms out. Add a setting
to disable this behaviour.

* Source/WTF/Scripts/Preferences/UnifiedWebPreferences.yaml: Add a
    new setting AudioControlsScaleWithPageZoom to mirror the generic
    Media setting.
* Source/WebCore/html/HTMLMediaElement.cpp:
(WebCore::HTMLMediaElement::setMediaControlsDependOnPageScaleFactor): Add
    a test that escapes before setting the value.
