Build: Generate the slim build on grunt & run compare_size on it
Summary of the changes: * expand `node_smoke_tests` to test the full & slim builds * run `compare_size` on all built minified files; don't run it anymore on unminified files where they don't provide lots of value The main goal of this change is to make it easier to compare sizes of both the full & slim builds between the `3.x-stable` & `main` branches. Closes gh-5291 Ref gh-5255 (partially cherry-picked from commit 8be4c0e)

##### File name

The default name for the built jQuery file is `jquery.js`; it is placed under the `dist/` directory. It's possible to change the file name using the `--filename` parameter:

136+
```bash
137+
grunt custom:slim --filename="jquery.slim.js"

```

This would create a slim version of jQuery and place it under `dist/jquery.slim.js`. In fact, this is exactly the command we use to generate the slim jQuery during the release process.
