[iOS] Set background playback restriction for WebAudio https://bugs.webkit.org/show_bug.cgi?id=220879 <rdar://72949281> Reviewed by Jer Noble. Source/WebCore: WebAudio does not play in the background on iOS both because audio doesn't play when the category is set to `AVAudioSessionCategoryAmbient`, and because the AudioContext is paused when the web process is forwarded the `UIApplicationWillResignActiveNotification` notification. This notification isn't forwarded when the WebView is hosted in SafariViewController so the AudioContext is not paused, so it resumes playing when the application is foregrounded even if the view controller is not in the foreground. Fix this by setting the `BackgroundProcessPlaybackRestricted` restriction for WebAudio sessions so the context is always paused in the background.
