The Arcade Physics Body.setGameObject and `StaticBody.setGameObject…

…` methods have been updated to do the following: Return if no valid Game Object is passed. Disable and null the body of the existing Game Object if the Body has one. Set the `body` property, even if it doesn't exist (converts non-physics objects into physics objects). Calls `setSize` to update the body dimensions to make the new Game Object and finally sets `enable` based on the given parameter, which is now correctly referenced. The StaticBody version also has a new parameter, `enable` which matches that of the Dynamic Body and defaults to `true` (the original state). Fix #6969
