fix SIM related VTS failures

1. Add 6s delay after setSimSlotsMapping because modem needs time to
   process SIM configuration change. The next TC could fail at
   checking SIM status if there is no delay. The default SIM
   configuration on my test device is that physical#0 maps to
   logical#1 and physical#1 maps to logical#0. When running
   setSimSlotsMapping, it then becomes physical#0 maps to logical#0
   and physical#1 maps to logical#1.
2. Support DSDS case and TSTS case for setSimSlotsMapping. The
   original code only set for 1 slot and it caused 2nd slot SIM
   absent when testing with DSDS enabled.
3. Set slotStatus from corresponding physical slot for
   setSimCardPower.
