The test was explicitly tiering up or down a module, without respecting
other isolates. Thus it was failing in multi-isolate mode.
This CL removes two runtime functions which do not make sense in a
multi-isolate setting (and were only used in this one test), and
replaces them with runtime functions that mimic what enabling/disabling
the debugger domain does: As long as there is at least one isolate which
needs modules to be tiered down, we keep them tiered down.
