gziolo 355c05ea71 Build Tools: Integrate DependencyExtractionWebpackPlugin in the JS build.
This patch integrates DependencyExtractionWebpackPlugin which was battle-tested in Gutenberg. 

This will greatly simplify the process of upgrading npm packages which change after every Gutenberg release. It might even useful during the WordPress release cycle as we might need to publish more often as we discover critical bugs and regressions.

Props jonsurrell, adamsilverstein, youknowriad, ocean90, netweb.

Fixes #48154.
