Checks if a transport is currently attached for a given association id.
A transport is considered attached if attachSystemDataTransport(int,InputStream,OutputStream) has been successfully called for the given associationId, and detachSystemDataTransport(int) has not yet been called.
This is useful for determining if the system is ready to handle data transfers before calling startSystemDataTransfer(int,Executor,OutcomeReceiver).
The caller must meet one of the following requirements: It is the package that originally created the association; It holds the android.permission.ACCESS_COMPANION_MESSAGE_PCC permission and the association must be verified as a trusted device
