DEV: Fail core JS test runs if deprecations are triggered ()
It's important to keep our core log output as clean as possible to avoid 'crying wolf', and so that any deprecations triggered by plugin/theme tests are indeed caused by that theme/plugin, and not core.

This commit will make the core test suite fail if any deprecations are triggered. If a new deprecation is introduced (e.g. as part of a dependency update) and we need more time to resolve it it can be silenced via ember-deprecation-workflow.

This does not affect plugin/theme test runs.
