Don't use the task for a cache, return a special cache var (#47243)

Browse source 
* Don't use task to cache loop results, use hostvars. Fixes #47207

* Avoid a race condition, supply _ansible_loop_cache through get_vars directly

* Add tests

* Add changelog fragment

* Remove unnecessary copy

* Remove unnecessary host from _get_delegated_vars signature
