Convert BsForm to Glimmer component

[simonihmig]

Also fixes tests to test real validation plugin interface, closes #1338

@jelhan we might need to update ember-bootstrap-cp-validations and ember-bootstrap-changeset-validations after landing this I guess? For them it might be a breaking change, while users should not be affected as they are not allowed to subclass components. But as we consider them "privileged" addons, we won't bump a major here, I think we agreed on that, right?

OK, due to the use of a component class (vs. component definition as with the {{component}} helper) tests are failing for older Ember. But I think I know how to fix. Also need to look into Embroider, but not today anymore...

I tested the changes locally with ember-bootstrap-cp-validations, and everything seems to work fine. ember-bootstrap-changeset-validations however fails. It is still using the legacy object model: https://github.com/kaliber5/ember-bootstrap-changeset-validations/blob/master/addon/components/bs-form.js#L6 🙁

So until that is fixed, I'll keep this open...

Good catch. I created an issue in that repository to track: ember-bootstrap/ember-bootstrap-changeset-validations#39 Sadly I don't have time to pick it up right now.

I'll merge this now, as the fix on the ember-bootstrap-changeset-validations side has been merged as well. Will then cut a release for both addons soon...
