Add a class method to the debugger-class. return true/false,
depending on the availability of the feature.
The base class, would have the current ifdef. All other code depends on
the value of the method.
In ide/DebugManager the debugger class is selected and setup. That would
be the place to update the menu (maybe enable/disable instead of hiding).
 If it is a class method debug manager may be able to decide on the
class. If the code in debug manager allows to wait for the instance,
then it can be a normal method.
