fix: proxy ios webkit events into fullscreenchange (#3644)

Browse Source 
iOS still doesn't have native fullscreen API access. The video element uses the old webkit fullscreen events `webkitbeginfullscreen` and `webkitendfullscreen`. This makes it so both of those trigger `fullscreenchange` on the player always as opposed to only when `requestFullscreen` was called on the player.
