Move request sync logic into GoogleConfig (#28227)

* Move request sync logic into GoogleConfig

* Return http status code for request_sync same as cloud

* agent_user_id is not optional for async_sync_entities now

* No need in checking parameter here

* Adjust some things for cloud tests

* Adjust some more stuff for cloud tests

* Drop uneccessary else

* Black required change

* Let async_schedule_google_sync take agent_user_id

* Assert return value on api call

* Test old api key method

* Update homeassistant/components/google_assistant/helpers.py
