Is your feature request related to a problem? Please describe.

In some scenarios for me (normally when using Stripe Connect), we don't have enough information to create a Stripe instance until we have parsed the webhook event.

Specifically, we may need the Event.account property to determine what credentials/API key to use to create a Stripe instance.

However, the Stripe.Webhooks utility is only available after creating a Stripe instance.

Describe the solution you'd like

After inspecting the code, it seems the webhook utilities instance does not depend at all on a specific Stripe instance.

This webhook utilites instance could be made available as a static property on the Stripe constructor, and that instance also shared on the individual instances.

Like so:

const Stripe = require('stripe');

// Available as a static property
Stripe.webhooks.constructEventAsync(...);

// Remains available on the instance also
const client = Stripe('...');
client.webhooks === Stripe.webhooks // true

Happy to help with a PR if you agree with the logic.

Describe alternatives you've considered

A workaround is using new Stripe('').webhooks to get an instance of the webhook utilities, but it feels like a hack, because it relies on the internal workings of the Stripe() constructor not attempting to validate the empty API key.
