🐛 [amp-jwplayer] Allow video docking during ad playback

[zetagame]

This PR reverts amp-jwplayer to dispatching VideoEvents_Enum.PLAYING and VideoEvents_Enum.PAUSE on adPlay and adPause to allow for video docking during ad playback. In addition, element now triggers VideoEvents_Enum.PLAY on first playback of a playlist item to prevent redispatch of VideoAnalyticsEvents_Enum.PLAY on subsequent plays of a playlist item.

Note: There is a test failing on e2e but it is marked as flaky and shouldn't be affected by these changes.
