Add `debounce` config stub

[jpwilliams]

Summary

Adds support for debounce by adding the simple config debounce.period and debounce.key made available in inngest/inngest#612.

inngest.createFunction(
  {
    id: "debounce-example",
    debounce: {
      period: "5m",
      key: "event.data.userId",
    },
  },
  { event: "app/something.happened" },
  async ({ event, step }) => {
    // ...
  }
);

Like concurrency and idempotency, debounce.key is just a string. We can later ensure that we provide typing based on the triggering event(s), similar to step.waitForEvent().
