2d CameraManager do not unregister RESIZE event when be destroyed

[liuhongxuan23]

Version

• Phaser Version: v3.55.2

Description

https://github.com/photonstorm/phaser/blob/5c8ecbcf999e6f328d21884e877c9e5935d2d350/src/cameras/2d/CameraManager.js

The event is registered at line 163, but will never be unregistered. This will introduce garbage objects if we continuously create and destroy scenes.

sys.game.scale.on(ScaleEvents.RESIZE, this.onResize, this);

Example Test Code

var game = new Phaser.Game({});

game.scene.add("dummy", {}, true);
setInterval(function () {
    game.scene.remove("dummy");
    game.scene.add("dummy", {}, true);
    console.log(game.scale.listenerCount("resize"));
} ,1000);
