Determines the video support of the browser running this Phaser Game instance.
These values are read-only and populated during the boot sequence of the game.
They are then referenced by internal game systems and are available for you to access
via `this.sys.game.device.video` from within any Scene.

In Phaser 3.20 the properties were renamed to drop the 'Video' suffix.
