Reproduce states by letting each component opt in on handling state recovery itself (#18700)

* Move group to it's own setup

* Let each component to handle restore of state

* Move constants for climate into const.py

For now import all into __init__.py to keep backword compat

* Move media plyaer constants to const.py file

For now import all constants into __init__.py to keep
backword compatibility

* Move media player to it's own file

* Move climate to it's own file

* Remove ecobee service from common components

BREAKING CHANGE

* Add tests for climate

* Add test for media_player

* Make sure we clone timestamps of state

* Add tests for groups

* Remove old tests for media player, it's handled by other tests

* Add tests for calls to component functions

* Add docstring for climate const

* Add docstring for media_player const

* Explicitly import constants in climate

* Explicitly import constants in media_player

* Add period to climate const

* Add period to media_player const

* Fix some lint errors in climate

* Fix some lint errors in media_player

* Fix lint warnings on climate tests

* Fix lint warnings on group tests

* Fix lint warnings on media_player tests

* Fix lint warnings on state tests

* Adjust indent for state tests
