sim-uicc: new interface for uicc esim functionality

When third party LPA need to be integrated in linux for any profile operations such as profile download, profile upload, profile status, profile enable, profile disable,etc then there is no MM interface and it has to be integrated with either libmbim or via AT port. With this proposal there will be a common interface for uicc esim functionality which will abstract the underlying protocol(MBIM or AT), thus enabling any third party esim LPA vendor to seamlessly support esim operations.
