Update fitbit device fetch to use a data update coordinator (#101619)

* Add a fitbit device update coordinator

* Remove unnecessary debug output

* Update comments

* Update fitbit coordinator exception handling and test coverage

* Handle reauth failures in other sensors

* Fix scope changes after rebase.
