In Matter.js if you scaled a Body it would only scale correctly once, due to the way Matter handles scaling internally. We now automatically reset the Matter scale before applying the new value, which allows you to keep the Phaser and Matter object scales in sync. Fix #3785 #3951

* The calls to `DistanceBetween` have been replaced with `DistanceSquared` in the `closest` and `furthest` functions within Arcade Physics (thanks @Mursaat)
* The RandomDataGenerator will now create a default random seed if you instantiate your own version of the class (instead of using `Phaser.Math.RND`) and don't provide a seed for it (thanks michaeld)
* The Tilemap `createFromObjects` method will now add custom properties to the Game Objects. It works by checking if the property exists or not, and if not, it sets it in the Game Objects Data Manager (thanks @scalemailted @samme)
