Media Session: generalize isFocusedContentMediaElementPlaying so it works with other playback attributes

[Matt Rajca]

Media Session Focus manager's 'isFocusedContentMediaElementPlaying' method will be refactored to a more general 'valueForPlaybackAttribute' so it works with other attributes (IsNextTrackControlEnabled and IsPreviousTrackControlEnabled).

I removed this include after sending out the patch since we don't need it here.

Using a HashMap here is overkill, especially since you could put WKMediaSessionFocusManagerPlaybackAttribute into a bit mask.

This should be enum WKMediaSessionFocusManagerPlaybackAttribute {  ... }
typedef uint32_t WKMediaSessionFocusManagerPlaybackAttributes;

No need to name the parameters here.
