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.

Changes of note:
- Includes the new Annotations API package.
- `wp-polyfill-ecmascript.js` is renamed to `wp-polyfill.js`.
- `strip_dynamic_blocks()` has been removed in favor of `excerpt_remove_blocks()`.
- The PHP block parser is now syncing from the `block-serialization-default-parser` package.
- `do_blocks()` uses the new parser.
- The `do_block` filter has been removed from `do_blocks()`, in favor of a `render_block` filter in `render_block()`.
Also, a little cleanup to `render_block()`. Always normalize `$block['attrs’]` to array in `’render_block’` filter.
Props pento, azaozz.

CSS coming from the `@wordpress` packages wasn't being minified in the build. This had the noteable side effect of causing RTL CSS to not be loaded when `SCRIPT_DEBUG` was set to `false`.
