In our legacy environment, Ember RFC176 shims are included in `discourse-loader.js` which is part of the `vendor.js` bundle. This meant that the module shims were available as soon as the vendor.js asset was loaded. Under Ember CLI, we were defining these shims in `discourse-boot.js`. This is loaded by the browser much later, and meant that the shims were not available to themes/plugins that call `require()` before Discourse has booted. This was causing errors under some circumstances. This commit refactors the Ember CLI implementation so that the shims are included in the vendor.js bundle. This is done via an addon which leans on the ember-rfc176-data NPM package. This will ensure we have all the definitions, without the need for manual copy/paste.
