If multiple isolates are using the same module, we need to keep it
tiered down as long as any isolate still has a debugger open.
Also, we cannot short-cut the {NativeModule::TierDown} method, since the
previously triggered tier down might not have finished yet.
For now, each isolate starts an independent tier down (i.e. a full
recompilation). We could optimize this later by skipping functions that
are already tiered down, or are already scheduled for tier down, but we
still need to wait for tier-down to finish on each isolate.
