This is similar to ec69b4bb1256c061ac76f53dfed09c4283ec6a31, which was about private instance fields. Private properties can be non-writable (thanks to decorators), or have get/set accessors. If we stored this information on the `privateClass` object, we would need to always use `Object.getOwnPropertyDescriptor` before reading or writing a property because accessors need to be called with the correct `this` context (it should be the actual class, not the object hat stores the private properties). This commit simplifies that operation a bit by removing the container object. It also have another advantage, which instance fields already have thanks to the use of separate weakmaps: unused private static fields can be tree-shaken away or garbage-collected, while properties of an object can't. Also, they can be easilier minified.
