Original commit message:
[api] Add Context::GetMicrotaskQueue method
Add a method that returns the microtask queue that is being used
by the `v8::Context`.
This is helpful in non-monolithic embedders like Node.js, which
accept Contexts created by its own embedders like Electron, or
for native Node.js addons. In particular, it enables:
1. Making sure that “nested” `Context`s use the correct microtask
queue, i.e. the one from the outer Context.
2. Enqueueing microtasks into the correct microtask queue.
Previously, these things only worked when the microtask queue for
a given Context was the Isolate’s default queue.
As an alternative, I considered adding a way to make new `Context`s
inherit the queue from the `Context` that was entered at the time
of their creation, but that seemed a bit more “magic”, less flexible,
and didn’t take care of concern 2 listed above.

Fall back to using the outer context’s microtask queue, rather than the Isolate’s default one. This would otherwise result in surprising behavior if an embedder specified a custom microtask queue for the main Node.js context.

That's equivalent right now, yes, but I'd like to write this in a more future-proof way if you don't mind :)

There will be situations where the active environment doesn't match the active context?

Well, we could extend Node.js to supporting multiple different Contexts per Environment, which would be nice, and we’re not that far from supporting it
