Add STATE_USER_PROFILE_FINALIZED as an additional user state

This will be used as an intermediate state after
STATE_USER_PROFILE_COMPLETE once the work profile has been created.

With the current admin-integrated flow refactoring changes,
the work profile will be finalized earlier than before.
Therefore, we add this new state so that SetupWizard
can differentiate between this state and STATE_USER_UNMANAGED.

Instead of the user states for work profile provisioning being
STATE_USER_UNMANAGED -> STATE_USER_PROFILE_COMPLETE ->
STATE_USER_UNMANAGED, they will now be STATE_USER_UNMANAGED ->
STATE_USER_PROFILE_COMPLETE -> STATE_USER_PROFILE_FINALIZED.

Note that CTS testing this API is infeasible, since it's
a system API and it requires the MANAGE_PROFILE_AND_DEVICE_OWNERS
signature permission which can't be granted to a CTS app.
