This change makes CTX available by not caching the current context while in Dart code. Instead the current context is held in a local variable (:saved_current_context_var) and is passed as argument in CTX at calls. This also simplifies a lot of code in the debugger: As a result, Isolate::top_context is not needed anymore since the current context can always be extracted from a Dart frame.
