Subject: Separate SIM states from Radio states

Radio state reflects the state of the modem. SIM_READY, RUIM_READY,
NV_READY are subscription states and it is possible that the new cards
have multiple subscriptions. Remove the SIM states from Radio State and
introduce a new VOICE_RADIO_TECH message to identify the exact voice
technology. SIM states will continue to be identified from the
SIM_STATUS messages.
