These annotations make it clear to the reader of a JavaScript source where the build process outputs to. These annotations can later be integrated in a webpack configuration. This way there is one source of truth. The `build` folder is omitted from the paths, because a single JS file shouldn't not be responsible of knowing where outputs in general will end up at. A file only knows its output location relative to the project. Props adamsilverstein, herregroen, omarreiss, pento. Fixes #44361. Built from https://develop.svn.wordpress.org/trunk@43347 git-svn-id: http://core.svn.wordpress.org/trunk@43175 1a063a9b-81f0-0310-95a4-ce76da25c4cd
