Move the JS content handler et al from mojo/apps/js to mojo/services

Moved the JS content handler, the gl and monotonic_clock modules from mojo/apps/js to services/js.

Added the following main directories:
mojo/services/public/js - The JS content handler client module.
services/js - The JS content handler implementation.
services/js/modules - The gl and clock modules.
examples/js - Mostly a TBD.

Added js_services_unittests.

This should the last big file shuffle for JS in Mojo.

PTAL. Notes:

- My GN skills are still pretty lame. 

- I put a DEPS file in mojo/services/js that DTRT, not sure what rules to follow
there.

- These files look wrong: mojo/mojo_apps_js_unittests.isolate 
mojo/mojo_js_unittests.isolate. For example the unit test executables don't have
a "mojo_" prefix. Do they need to be updated?

drive-by: you should move this into //services not //mojo/services.
//mojo/services is deprecated and will die once colin is done with the
sdk-ification.

I moved mojo/services/js to services/js.

You're right. The JS GL bindings haven't been exercised in a while. I'm going to
try and resurrect Aaron's old GL demo this week.
