Mojo JS standalone app launches files specified with mojo_shell command-line args

Mojo JS standalone app launches files specified with mojo_shell command-line args

Arguments specified with the mojo_js_standalone app URL are loaded and run. Each argument is run on a separate thread, in its own V8 isolate. For example:

  mojo_shell 'mojo:mojo_js_standalone foo.js bar.js'

Also: moved the one-time gin V8 initialization from JSApp - where it could be called from multiple threads - to ApplicationDelegateImpl::Initialize(). Where it's called once, before any JSApp's are started.

This is a tiny change that uses the command-line argument feature I added in
https://codereview.chromium.org/617943002 to specify JS files to run for
mojo://mojo_js_standalone.

PTAL
