Automatically enable coroutine debugging in DEBUG and test builds. (#1060)...

Automatically enable coroutine debugging in DEBUG and test builds. (#1060) (Spawned by EXPOSUREAPP-2267)

* Automatically enable coroutine debugging in DEBUG and test builds.
CWADebug should be used as abstraction for enabling additional non-production debug features and modes.
In the future we can use this abstraction to enable additional debugging options in productions builds.
Sometimes that's the only way to debug issues that can't be reproduced by developers.

* Fix LINTing
