Add hassio addon_update service and hassio config entry with addon and OS devices and entities (#46342)

* add addon_update service, use config flow to set up config entry, create disabled sensors

* move most of entity logic to common entity class, improve device info, get rid of config_flow user step

* fix setup logic

* additional refactor

* fix refactored logic

* fix config flow tests

* add test for addon_update service and get_addons_info

* add entry setup and unload test and fix update coordinator

* handle if entry setup calls unload

* return nothing for coordinator if entry is being reloaded because coordinator will get recreated anyway

* remove entry when HA instance is no longer hassio and add corresponding test

* handle adding and removing device registry entries

* better config entry reload logic

* fix comment

* bugfix

* fix flake error

* switch pass to return

* use repository attribute for model and fallback to url

* use custom 'system' source since hassio source is misleading

* Update homeassistant/components/hassio/entity.py

* prefix one more function with async and fix tests

* use supervisor info for addons since list is already filtered on what's installed

* remove unused service

* update sensor names

* remove added handler function

* use walrus

* add OS device and sensors

* fix

* re-add addon_update service schema

* add more test coverage and exclude entities from tests

* check if instance is using hass OS in order to create OS entities
