fix: let Node.js perform microtask checkpoint in the main process (#24131)

* fix: let Node.js perform microtask checkpoint in the main process

* fix: don't specify v8::MicrotasksScope for explicit policy

* fix: remove checkpoint from some call-sites

We already perform checkpoint at the end of a task,
either through MicrotaskRunner or through NodeBindings.
There isn't a need to add them again when calling into JS
except when dealing with promises.
