REGRESSION(262981@main): [iOS] WebKit never activates its AVAudioSession
https://bugs.webkit.org/show_bug.cgi?id=257309
rdar://109817291

Reviewed by Eric Carlson and Youenn Fablet.

In 262981@main, the contents of AudioSessionIOS::tryToSetActiveInternal() were moved into
a new common base class of AudioSessionIOS and AudioSessionMac: AudioSessionCocoa.

However, that patch neglected to make AudioSessionCocoa a base class of AudioSessionIOS.
This had the effect of removing audio session activation entirely from the iOS port of
WebKit.
