This makes sure we don't use es6 syntax when compiling the `web-vitals` package with `ncc` since that breaks IE11 compatibility 

x-ref: https://github.com/vercel/ncc/pull/614

This upgrades to ncc@0.25.0 and fixes the previous bugs including:

* ncc not referenced correctly in build
* Babel type errors
* node-fetch, etag, chalk and raw-body dependencies not building with ncc - these have been "un-ncc'd" for now. As they are relatively small dependencies, this doesn't seem too much of an issue and we can follow up in the tracking ncc issue at https://github.com/vercel/ncc/issues/612.
* `yarn dev` issues

Took a lot of bisecting, but the overall diff isn't too bad here in the end.

This fixes the current regression with an ncc revert for now.

I will continue to follow up with the ncc upgrade in https://github.com/vercel/next.js/pull/18860.

This updates to the latest ncc@0.24.1 release.

Initially I thought chalk needed to be removed to make this work, but it turns out it was a caching issue.

I've also added a cache clear to the rebuild command to avoid these issues hopefully in future.
