Improve & fix Mono build

- Fix C++ compile errors about pending variable renames after the `Reference` to `RefCount` change.
- Fix C# compile errors due to the recent rename of `EnablePlugin()` and `Build()`, which are now underscore-prefixed in bindings.
- Additional rename: `godot_icall_Reference_Dtor` to  `godot_icall_RefCounted_Dtor`.
