Adding support for SIM communication from Android over logical channels.

Browse Source 
Expose the folowing commands in ITelephony.aidl and TelephonyManager:
    - iccOpenLogicalChannel
    - iccCloseLogicalChannel
    - iccTransmitApduLogicalChannel

Also add a new SIM_COMMUNICATION permission (maked as dangerous) to control
access to the above commands.
