The tests added in https://github.com/vercel/next.js/pull/46219 were
never correctly testing the headers because `detectContentType()` is
called first and only when we can't detect the type from the response
body do we fallback to the `Content-Type` header.
I also refactored some of the tests because the `ctx: any` type was
causing some tests to not run when testing different configuration
options.
Closes NEXT-3321
### Fixing a bug
### What?
Fix remotePatterns when all paths and/or domains are allowed.
### Why?
micromatch creates a very strange regex for all paths -
`/^(?:(?!\.)(?:(?:(?!(?:^|[\\/])\.).)*?)[\\/]?)$/`. That is, paths
cannot start with a dot or contain a slash followed by a dot.
Interestingly, here are some valid paths:
- /a/a.a/6a00d8341c4fbe53ef02c8d3a82122200d-600wi
- ////a/a.a/6a00d8341c4fbe53ef02c8d3a82122200d-600wi
- ///:?%;№%/a/a.a/6a00d8341c4fbe53ef02c8d3a82122200d-600wi.\/
- /:./6a00d8341c4fbe53ef02c8d3a82122200d-600wi.\/
And here are some invalid ones:
- /.a/6a00d8341c4fbe53ef02c8d3a82122200d-600wi
- /a/.a/6a00d8341c4fbe53ef02c8d3a82122200d-600wi
- ./a/6a00d8341c4fbe53ef02c8d3a82122200d-600wi
I don't think this check makes any sense.
### How?
If the user allows all (`**`) - it means any path or domain will be
considered valid.

## Description
This PR implements a new configuration object in `next.config.js` called `experimental.images.remotePatterns`.
This will eventually deprecate `images.domains` because it covers the same use cases and more by allowing wildcard pattern matching on `hostname` and `pathname` and also allows restricting `protocol` and `port`.
