[iOS] Do not pause playing video when application resigns active state.
https://bugs.webkit.org/show_bug.cgi?id=173474

Reviewed by Tim Horton.

Source/WebCore:

Test: media/video-inactive-playback.html

Separate out the concept of "inactive" playback from "process background" playback.
Move the implementation of applicationDidEnterBackground() from MediaSessionManagerIOS
into it's superclass, PlatformMediaSessionManager, and add a new set of restrictions
for "InactiveProcessPlaybackRestricted" and "SuspendedUnderLockPlaybackRestricted".
Leave the default restriction set for iOS as "BackgroundProcessPlaybackRestricted" and
"SuspendedUnderLockPlaybackRestricted", to preserve the existing behavior of suspending
playback when switching apps or when locking the device.
