Also,
1. Consistent CORS support ~on all three webhook types~ waiting webhooks never supported CORS. I'll fix that in another PR
2. [Fixes binary-data handling when request body is text, json, or xml](https://linear.app/n8n/issue/NODE-505/webhook-binary-data-handling-fails-for-textplain-files).
3. Reduced number of middleware that each request has to go through.
4. Removed the need to maintain webhook endpoints in the auth-exception list.
5. Skip all middlewares (apart from `compression`) on Webhook routes.
6. move `multipart/form-data` support out of individual nodes
7. upgrade `formidable`
8. fix the filenames on binary-data in webhooks nodes
9. add unit tests and integration tests for webhook request handling, and increase test coverage
