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 git-svn-id: http://core.svn.wordpress.org/trunk@43942 1a063a9b-81f0-0310-95a4-ce76da25c4cd
