Wait for the on-going APDU command procedure for eSIM

The mechanism for sending APDU command to eSIM must be used by a single
LPAd client at a time, but EuiccCard also sends a command for retrieving
EID if the terminal does not support the radio HAL v1.4 nor later one.
ApduSender must have a waiting logic to avoid rejecting APDU command
request from LPAd while ApduSender is handling the internal request.
