Convert nws integration to component configuration (#31398)

* convert nws to component configuration

* add more debug logging

* remove assumed state

* move initialization of data into init

* refactor update logic

* use forecast success for checking available entities

* Split unique_id into more usable pieces.

use a base_unique_id for each entry.  Add domain for signaling to entities.  Each entity in each platform can use base_unique_id to form individual unique_id's.

* Revert "move initialization of data into init"

This reverts commit 09eb0220469285b10f0500f5f6def67415931a81.

* add silver quality scale to manifest

* unsubscribe listener in will_remove_from_hass

* initialize _unsub_listener in __init__

* use async_on_remove

* remove scan interval from configuration

* Use better name
