Detailed Description

This scope is used to control microtasks when MicrotasksPolicy::kScoped is used on Isolate. In this mode every non-primitive call to V8 should be done inside some MicrotasksScope. Microtasks are executed when topmost MicrotasksScope marked as kRunMicrotasks exits. kDoNotRunMicrotasks should be used to annotate calls not intended to trigger microtasks.
