* 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.
