wgl: Do not reach out and destroy contexts on cleanup.
Simply skip cleanup when contexts are still active. This addresses two issues: - in some situations the ICD DLL may be unloaded before the DLL that is using GL contexts is, so we may receive GL calls after stw_cleanup. - when aborting (exception, or control-c) the contexts may have been left in an inconsistent state and attempting to destroy can cause unpredictable results.
