WordPress/js/dist/dom.js
atimmer 8614d14887 Build tools: Build @wordpress packages with webpack. 
We decided to split the media webpack config into it's own file. The
main webpack config then combines this file with the packages config.

Include vendor scripts by copying them. We copy the minified files if
they are available. If they aren't available we minify the original
files ourselves.

Props omarreiss, herregroen, gziolo, youknowriad, netweb, adamsilverstein.
Merges [43719] to trunk.
See #45065.

Built from https://develop.svn.wordpress.org/trunk@44112
