Update Grunt to version 1.0.2

[iandunn]

We're currently on Grunt 0.4.5, which is 1 major version behind the latest, 1.0.1.

Upgrading to the latest would benefit #42282, because it adds support for multiple values for command line parameters, e.g.,

grunt watch:phpunit --files=wp-includes/http.php --files=wp-includes/Requests --group=http

​Changes since 0.4.5.

I did some basic smoke testing with our existing tasks and the new version, but many of them fail with errors like, Warning: grunt.util._.flattenDeep is not a function Use --force to continue. It seems like that's caused by ​dependencies that aren't compatible with Grunt 1.0.0.

I tried upgrading some of them, but it didn't seem to work in all cases. I don't have time to dig any deeper right now, though.

Thanks @iandunn, agreed, a great enhancement for what's going on in #42282

That said, let's do this in 5.0, I don't want to update any of these npm dependencies for 4.9 as we're now in beta.

And now with that said, I also hit upon the same issues you've had here previously in #38199#comment:15

Once /trunk becomes 5.0 I'll refresh up the patch here and any update any other dependencies that require or have issues with Grunt 1.x (I'll also update any other dependencies in a separate ticket)

As an aside and related further are the handful of tasks in #35105 which relate to updates we need to perform on our "build server" to update NodeJS and npm versions and to ensure that our build tools updates don't break the build process for build.svn.w.org

Upgrading to the latest would benefit #42282, because it adds support for multiple values for command line parameters

That's no longer needed, since it's performant and better UX to just watch the whole repo instead.
