Change link_and_cleanup_shared_classes(CATCH) to CHECK

void MetaspaceShared::preload_and_dump_impl(TRAPS) {
   ...
     link_and_cleanup_shared_classes(CATCH);
  ...
}

But there's a valid reason for an exception to happen in this case:

link_and_cleanup_shared_classes
-> link_class_for_cds
  -> ik->constants()->resolve_class_constants(CHECK_(false)); // may throw OOM when interning strings.

We should propagate this exception back to MetaspaceShared::preload_and_dump, so it can be handled properly.
