feat: add support for query param url syntax of IMAGE CDN

[pieh]

Summary

gatsbyjs/gatsby#35160 changed the URL structure for image cdn. This PRs add support for new structure:

1. ODBs are cached just on path ignoring query params. New syntax allows for multiple images sharing same path and differ just with query params. To support it, permanent redirect is added that moves query params into path. That redirect doesn't match old structure and I don't think there's a way to match it there
2. The added redirect doesn't match the older structure (I don't think it's possible to actually match it with existing API given some encoding changes need to happen), so IPX handler wrapper now also converts event to match old structure. This means no changes are needed in @netlify/ipx. (I'm yet to figure out if this will make it possible to hit problems that caused Gatsby to change the url structure, but I'm hopeful it could be fine, because most references I found related to fs limitation when using IMAGE CDN api without actual CDN support for it, as Gatsby treats those then as local image processing jobs)
