This expands on https://github.com/vercel/next.js/issues/24070 and ensures we show the dev overlay for additional cases like where `_app` or `_document` have syntax errors causing compilation to not be able to complete. This achieves showing the dev overlay even when compilation fails from a syntax error by doing a third minimal compilation in development with the needed client-side assets to render the dev overlay.

This bumps the babel cache key since we modified the `react-loadable` babel plugin and we don't want any cached versions used since the module names generated in previous cached version won't match the newly expected values.

This ensures that a duplicate locale key is not prepended to the path when navigating back (using browsers back button) to the root path containing query parameters or a hash value.
Current behaviour:
* `/fr?value=1` -> `/fr/another` -> click browser back button -> `/fr/fr?value=1`
* `/fr?value=1` -> `/fr?value=2` -> click browser back button -> `/fr/fr?value=1`
* `/fr#section` -> `/fr/another` -> click browser back button -> `/fr/fr#section`
* `/fr#section` -> `/fr#another` -> click browser back button -> `/fr/fr#section`
Fix:
Remove query string or hash value from path before determining whether to add the locale to the path in `addLocale` function.

Fixes: #24287
Previously, we weren't recording most (all?) of the Next.js measurements like `Next.js-hydration` in Concurrent Mode. This was mainly because the new API doesn't accept a callback.
Instead of special casing this, I've refactored it so that the measurements are just recorded when Root first flushes (via `useLayoutEffect`), which should be more or less the same timing for the old API.
Concurrent Mode is a little trickier for two reasons:
1. Flushes might be (slightly) delayed due to time-slicing and prioritization
2. Selective hydration might skew measurements in cases where full hydration is aborted
I don't have a good answer for those yet, so they'll need to be addressed when the time comes.
This PR addresses the potential for memory leakage with the previous caching scheme; it should also be more efficient, resulting in fewer instances where a fresh Babel config must be generated. Documentation has been added, and `overrides` have been removed in favor of conditional plugins for consistency.
This approach is easier to break, in that `CharacteristicsGermaneToCaching` must be correct for all cases. However, it means that <= 8 configs will need to be generated within the context of a single thread, and the config-caching is about as fast as we can get it.
Solves an issue some users ran into where enabling webpack 5 highlighted a wrong JSON import where named exports were used for JSON data.
> Should not import the named export 'myValue' (imported as 'myValue') from default-exporting module (only default export is available soon)
Fixes the e2e PnP tests by updating `enhanced-resolve` to get the fix in https://github.com/webpack/enhanced-resolve/pull/289, the tests started failing in https://github.com/vercel/next.js/pull/23810

Noticed in this issue the reproduction was using `getStaticPaths` on a non-dynamic page incorrectly although we don't currently show an error for this.

This ensures we don't attempt adding a locale to a path when the locale is already present but in a different casing, this also ensures we successfully remove the locale if the casing differs in the path. Additional tests have been added in the `i18n-support` suites to ensure this is working correctly.

This fixes dynamic pages with `fallback: false` that don't have a matching path causing a 404 before rewrites are checked unexpectedly. This ensures we treat `fallback: false` pages as a match only if they also have a matching static path so that fallback rewrites can be triggered correctly. An additional test suite as been added to ensure this is working as expected.

relevant changes:
* performance improvements for `export *` and reexports
* fixes incorrect cache invalidation when new properties are added to the DefinePlugin (fixes#23901)
Just cleans up some code, doesn't change the underlying mechanism

This is a follow-up to https://github.com/vercel/next.js/pull/23588 to update to use a regex lexer to gather the named regex groups instead of attempting to gather them through executing the regex since it can fail to gather the regex groups when they are using specific matching. This also ensures we don't pass the value as a segment when value is defined and it doesn't use a capture group. Additional tests are added to cover these cases and documentation updated to reflect this.

This PR adds the deduplication logic to image optimizer so the cache will be reused as much as possible if there're multiple concurrent requests.
