#46973: refactor: Node.js temporary "explicit" microtask policy scope pattern
Merged
Description of Change
Introduces a ExplicitMicrotasksScope class to standardize the behavior of temporary switches to V8's "explicit" microtasks policy when running code that can trigger Node.js. Replaces a duplicated pattern in node_bindings.cc, electron_renderer_client.cc, and web_worker_observer.cc with a scope object (RAII) that ensures consistent policy change and restoration.
