Convert double interface into abstract class

In a future change, we can implement double in the core
library, eliminating class Double (using the patch class
feature).

I presume this is tied to the TODO you have in double.dart

Maybe you can add a TODO :
// remove once we add patching of double class.

TODO to remove this once patching of double class is implemented?
