This PR updates a few features from experimental to stable status:
- `next/future/image` component
- `remotePatterns` configuration
- `unoptimized` configuration
* test: cleanup telemetry integration test
Instead of constantly parsing the console output, parse the output
once, convert the entries in JavaScript objects, then compare them
logically rather than textually.
* Collect telemetry for next/future/image
Track adoption of next/future/image and add relevant test.
* Requires prerequisite PR https://github.com/vercel/next-telemetry/pull/84
This PR adds telemetry to send list of the experimental swc plugins from next.config.js. Implementation largely mimics existing plugins telemetry for next_package (https://github.com/vercel/next.js/blob/canary/packages/next/telemetry/events/plugins.ts), with small modification to read swc plugin package instead.
One notable difference is swc plugin telemetry can be sent without version. This is due to swc plugins can be specified with absolute path without any npm pkg resolutions.

This PR introduces a new experimental component, `next/future/image`, which is inspired by the existing experimental `layout="raw"`.
The difference is that much of the code has been deleted in order to reduce client-side code as well as reduce complexity:
- No `layout` prop
- No `loader` config (although `loader` prop works)
- No `IntersectionObserver`, use native `loading="lazy"`
- No `lazyBoundary`
- No `lazyRoot`
- No `fill` (yet) so width & height are required
- No `objectFit` (use `style` instead)
- No `objectPosition` (use `style` instead)
This improves performance because native `loading="lazy"` doesn't need to wait for React Hydration and client-side JS.
In a future PR, we will modify `next/image` to remove `layout="raw"` since this new component supersedes it.

This PR deprecates declaring a middleware under `pages` in favour of the project root naming it after `middleware` instead of `_middleware`. This is in the context of having a simpler execution model for middleware and also ships some refactor work. There is a ton of a code to be simplified after this deprecation but I think it is best to do it progressively.
With this PR, when in development, we will **fail** whenever we find a nested middleware but we do **not** include it in the compiler so if the project is using it, it will no longer work. For production we will **fail** too so it will not be possible to build and deploy a deprecated middleware. The error points to a page that should also be reviewed as part of **documentation**.
Aside from the deprecation, this migrates all middleware tests to work with a single middleware. It also splits tests into multiple folders to make them easier to isolate and work with. Finally it ships some small code refactor and simplifications.
## 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`.

Currently, we have telemetry to measure how ESLint is invoked,
but we do not have telemetry that tells us how many users have
disabled ESLint during build.
This commit adds a new feature, `build lint` to track this metric.

`optimizeCss` is a feature that inlines critical CSS using critters.
The Aurora team would like to gauge adoption rate for this feature.
