After the JavaScript reorganization in [43309], it was no longer possible to test WordPress from the `src` folder. That meant a build step was required to test PHP modifications. That is suboptimal as even a simple copy is slower than a web server just serving the new file.
We achieve building to `src` by setting a `WORKING_DIR` constant in the Gruntfile that is `build` by default, but changes to `src` when the `--dev` flag is present on any Grunt command. We provide sensible defaults so some commands, such as copying `version.php`, always build to `build`.
Because testing from `build` is no longer required, we change the messages present in `index.php` and `wp-admin/index.php` to be more broadly about building WordPress.
We also change the webpack config to have more straightforward behavior based on the `buildTarget` argument. It only determines the build target now and has no implicit behavior anymore. `grunt build` still works as it worked before, to make sure that the build server produces the same `wordpress.zip` we are used to.
We do all this instead of a symlink setup because symlinks don't work on every platform.

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.

* Minification is done by uglify, so disable that in the media build.
* The webpack boilerplate has changed, which explains the changes in the build files.
* ModuleConcatenationPlugin is enable by default for production builds so we don't have to specify that ourselves.
Merge notes: In `trunk` uglify isn't run on the media files after webpack, so webpack does need to do that. Newer webpack versions use `terser-webpack-plugin` as the default minification. Use the `uglifyjs-webpack-plugin` plugin to maintain the same behavior as before. We can look into terser as a minifier later.
