Delete outdated/unused crmExample Angular module

Overview

Deletes some unused test Angular code.

Technical Details

This gets us one step closer to being able to autoload core Angular modules via glob().

Comments

I don't have anything against example code. But if we were to have an example Angular module IMO it should be:

1. Updated with latest best-practices (components, standalone base-page, bind-to-controller, bootstrap3)
2. Packaged as an extension, like https://lab.civicrm.org/extensions/api4example/.

Since this example module is outdated, IMO it would require a complete rewrite to make it useful. And in the meantime, it's taking up space and making autoloading of core modules via glob() more complicated.
