Add Fullscreen for Web

This feature is not available in any of the platforms, according to this:

#58114

@ditman if I change the parameter to make controls = true fullscreen works great.

video_player_web.dart line 157
videoElement = VideoElement()
..src = uri
..autoplay = false
..controls = true
..style.border = 'none';

@Bilonik I understand that that can be done, however, the plugin needs to run consistently across all platforms. (Ideally we should think on how to add the full screen feature to all platforms, that's why I linked the global issue)
