DEV: Restore ember-this-fallback runtime components (#39662)
These were previously included in requirejs modules transitively, via
the `discourse-plugins` addon. That was removed in
b27530cdb1.

This commit adds the minimum required modules as vendored shims, and
adds a simple system spec to prevent future regressions of
hbs/this-fallback functionality.
