b4a5663c - `optimize_barrel` SWC transform and new `optimizePackageImports` config (#54572)

`optimize_barrel` SWC transform and new `optimizePackageImports` config (#54572) ## Implementation Base on #54530, we're implementing a `optimize_barrel` transform to optimize barrel files to only export the names we need. If the transformed file isn't a "barrel file", we just re-export the names from it without any transformation. Take `lucide-react` as an example, with #54530 we are able to transform ```js import { IceCream } from 'lucide-react' ``` to ```js import { IceCream } from '__barrel_optimize__?names=IceCream!=!lucide-react?__barrel_optimize_noop__=IceCream' ``` And then, we apply that new request with a new Webpack module rule to use the SWC loader with option `optimizeBarrelExports: ['IceCream']`, which eventually got passed to this new `optimize_barrel` transform and does the optimization. ## Notes We'll have to add a new `getModularizeImportAliases` alias list to map `lucide-react` to the ESM version, as we have the `['main', 'module']` resolve order for the server compiler. Otherwise this optimization doesn't work in that compiler. There's no e2e test added because it's already covered by the `modularize-imports` test as we removed the default `lucide-react` transform rules and it still works. We'll need to test other libs before migrating them to the new `optimizePackageImports` option. --- Closes #54571, closes #53605, closes #53789, closes #53894, closes #54063.
