Move Memchecks support out of debug only builds

It wouldn't impact performance until at least one memcheck is enabled.  Because of this, it can be used in release builds without much impact, the only thing that woudl change is the use of HasAny method instead of preprocessor conditionals.  Since the perforamnce decrease comes right when the first memcheck is added and restored when the last is removed, it basically is all beneficial and works the same way.
