DEV: Restore ember-this-fallback runtime components (#39662)

main ← ember-this-fallback-fix

merged 03:12PM - 30 Apr 26 UTC

These were previously included in requirejs modules transitively, via the `disco…urse-plugins` addon. That was removed in b27530cdb100c0b8c913ce37643db6613b0a3c08. 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.

Will also backport to 2026.4

Edit: now merged
