Matthew Beck b569f6e82b test(compiler-cli): add compliance case for @HostListener on a property

`@HostListener` is not limited to methods — it is equally valid on a property
holding a function, which is the idiomatic way to keep `this` bound:

    @HostListener('window:beforeunload', ['$event'])
    private onUnload = (event: BeforeUnloadEvent) => {...};

Every existing host-listener compliance case declares the handler as a method,
so the property form was uncovered. This adds a case exercising both a public
and a private function-valued property, one of them with a global (`window:`)
event target, and locks in the emitted chained `ɵɵlistener` calls plus
`ɵɵresolveWindow`.

Verified against all four compliance modes (full, partial/linked,
declaration-only); GOLDEN_PARTIAL.js regenerated via the golden update rule.

(cherry picked from commit d44b3224d9)
