Fix cloned rsx double drop (#2839)

* Implement Rc generational pointers

* Clean up error handling a bit

* start adding tests

* Simplify a few types

* Separate Rc and normal generational boxes

* Add tests for rc drop and read

* Move over the pointer instead of the data in ReadOnlySignal props

* Fix panic on ref drop and release mode builds
