New error reports when a device's remote-session registration has been revoked

What

A new error is now raised when the local machine's device registration has been removed from the account, as used by the device registry for cowork/remote-device sessions. This is logged with the telemetry event cowork_remote_device_registration_revoked.

Why

This gives a clearer, specific error when a device's remote-session access has been revoked, instead of it failing in a less identifiable way.
