eap_proxy: UI support to get the SIM information.

Framework sends an event GET_SIM_INFO to get the sim card
information such as type of the SIM (2G/3G) and No. of SIMs
supported by the build.
Based on this, the framework will decide which sim supports
what type of EAP methods (SIM/AKA)
msg format: no_of_sims=x sim1=a sim2=b
