This fixes a case where optional catch-all route values aren't normalized to an array properly when the `index` value is passed. An additional test case has been added to prevent regressing on this.

This fixes our check for fallback pages during `next export` as we are currently erroring even when the erroneous pages are not included in the `exportPathMap`. This also adds additional tests to certify the expected behavior for the error.

Fixes: https://github.com/vercel/next.js/issues/29135
Production middlewares will only expose env vars that are statically analyzable, as mentioned here: https://nextjs.org/docs/api-reference/next/server#how-do-i-access-environment-variables
This creates some incompatibility with `next dev` and `next start`, where all `process.env` data is shared and can lead to unexpected behavior in runtime.
This PR fixes it by limiting the data in `process.env` with the inferred env vars from the code usage. I believe the test speaks for itself 🕺

After discussing with @sokra, seems that the proposed solution is split in two:
* We need to make sure that the `process` polyfill uses `global.process` if available. This is because middlewares are bundled using `browser` target and therefore `process.env.MY_ENV` gets shimmed into `require('process').env.MY_ENV`.
* Allow `process.env` to be statically analyzed for dependencies so they will be exported to the manifest.

* should fix#33043.
it should not leak into the client runtime

This reverts the type for the `conf` field in `ServerOptions` isn't changed to require all `NextConfig` values as this is a breaking change from what was previously required. We should investigate making sure this field is normalized when it is provided via a user.

This ensures type checking passes correctly for middleware types when `skipLibCheck: false` is set in `tsconfig.json`. This also moves the `middleware-types` to be an isolated test to ensure it isn't relying on any monorepo dependencies.

Fixes: https://github.com/vercel/next.js/issues/31992#issuecomment-984174872
This ensures the `asPath` and `req.url` values are normalized correctly for fallback pages with i18n in minimal mode. This also copies the minimal mode test suite to run against i18n as well. This also fixes an issue where rewrite params weren't passed correctly on the client when no params were already used in the destination.
The provided reproduction has been deployed against this patch [here](https://nextjs-error-repro-9zdu3sp5r-ijjk-testing.vercel.app/page/test-page) show it working.

This ensures we handle decode failures in minimal mode as a 400 response (bad request) instead of a 500 (server error).

As discussed this moves tracing `next-server` into `next build` since the pre-trace at publish time isn't able to reliably give us file locations since `node_module` file locations can vary based on installation. This also adds caching the trace so that we only need to retrace `next-server` when a lockfile changes.
A follow-up PR will add documentation for these traces explaining how they can be leveraged.
