Reland of #21163. With fixes to flow and a few extra callers.

Type the isArray function with refinement support

This ensures that an argument gets refined just like it does if isArray is
used directly.

I'm not sure how to express with just a direct reference so I added a
function wrapper and confirmed that this does get inlined properly by
closure compiler.

Why can't you just export Array.isArray? Is this to work around a Flow issue?

Or rather, to work around my lack of knowledge if there is a way in Flow to express this function declaration without an actual function.

This is not testing a bundle.
