Wire up key definitions for OrganizationService (#7781)

* Wire up key definitions for OrganizationService

[`AC-2009`: Transition OrganizationService to use StateProvider](
https://bitwarden.atlassian.net/browse/AC-2009)

In order to support the new `StateProvider` APIs for managing
application state this commit modifies `OrganizationService` in the following
ways:

1. Adding a `KeyDefinition` object to `OrganizationService` to store the
   `organization` record in `StateProvider`.
1. Injecting `StateProvider` and wiring up `OrganizationService` to read
   from the `organizations` key definition for the active user account.
1. Expanding the capabilities of `OrganizationData` to be able to read
   itself from a JSON string. Previously this was handled directly by
   `StateService`.
1. Updating tests to include requirements for testing against
   `StateProvider`.
1. Marking the existing `StateService`-backed `organizations`
   `Observable` and `BehaviorSubject` as deprecated.

This is largely unimplemented code with no intended visible effects to
the system. Implementing getting & updating the `organizations` value
from `StateProvider` will the next step in this work.

* Rework null check on OrganizationData

* Remove deprecation signals for the time being

* Move key definition inline with its service

* Create date objects when deserialzing json from state
