Move code cache purging out of CodeCache::UnloadingScope

      Description

        Currently, in the destructor of CodeCache::UnloadingScope we flush/purge the code cache from dead nmethods.

        This is fairly surprising to do this in the destructor because the purging can take a very signficant amount of time (i.e. 90%+ of total class unloading time).

        Make the flushing/puring explicit.
