### Summary - Closes elastic#89741 This PR contains the resulting work of a massive effort that ports our on top bundler abstraction (called @kbn/optimizer) from Webpack v4 into Webpack v5. It's essential in terms of long term maintenance since v4 was not receiving updates any longer but will also unblock some new features that could be beneficial for our future DevEx endeavours. Next you can find a small list of all the accomplished tasks on this journey. ### Completed Tasks - [x] Upgrade dependencies to match the ones on webpack v5 - [x] Fix null-loader usages - [x] Fix raw-loader usages - [x] Fix file-loader usages - [x] Fix url-loader usages - [x] Fix `@kbn/optimizer-webpack-helpers` to support webpack v5 - [x] Adopt previous webpack v4 polyfill-all strategy with node-polyfill-webpack-plugin - [x] Fix theme-loader on @kbn/optimizer - [x] Migrate configurations and ad-hoc loader options on all webpack configs from v4 to v5 - [x] Fix @kbn/test jest resolver for file-loader cases - [x] Migrate public-path loader on UiSharedDeps - [x] Fix all usages of webpack-merge - [x] Migrate BundleRemoteModule - [x] Migrate BundleRemotesPlugin - [x] Correctly migrate PopulateBundleCachePlugin - [x] Correctly migrate BundleMetricsPlugin - [x] Check if the profiling plugins still work (--profile flag) - [x] Recover if possible the previous webpack v4 cacheGroup chunks rename to something like `data.plugin.chunk.0.js` - [x] Run `/ci` and make sure we get our first green CI, otherwise work on the errors until we do - [x] Profile and solve bottlenecks until we get a cold build performance similar to the one we had on webpack v4 (`node scripts/build_kibana_platform_plugins --no-cache`). - [x] OpenSSL Legacy Warnings: try to remove `--openssl-legacy-provider ` flags - [x] Add Webpack to Renovate config - [x] Explore removing `NodePolyfillPlugin` ([here](https://www.npmjs.com/package/node-polyfill-webpack-plugin)) and add each polyfill needed individually per each webpack config to check if we get smaller bundles. If we do it's better to go with the case by case need approach instead of deploying a bunch of polyfills with NodePolyfillPlugin. As another alternative, create a custom smaller plugin with only the union of all needed polyfills. - [x] Evaluate if we want to touch the resolutions on mainFields and conditionNames - [x] Understand why `@import 'src/core/public/mixins'` does not work anymore (not a problem, we should use relative paths anyway but we want to track why it changed from v4 to v5) - [x] BUG: Child compilers are having errors hidden and/or changed from error to warning - [x] Fix license check for [Artistic-2.0](https://spdx.org/licenses/Artistic-2.0.html) is the license for [domain-browser](https://github.com/bevry/domain-browser?tab=License-1-ov-file).

Summary
This PR contains the resulting work of a massive effort that ports our on top bundler abstraction (called @kbn/optimizer) from Webpack v4 into Webpack v5. It's essential in terms of long term maintenance since v4 was not receiving updates any longer but will also unblock some new features that could be beneficial for our future DevEx endeavours.
Next you can find a small list of all the accomplished tasks on this journey.
