MSIM: set phone account handle changes for ECall

Add interface API between Telephony to Telecomm for
updating phoneAcount.
Currently on multisim, Telephony(PhoneApp) picks the best
possible sub for placing emergency call, after selecting the
best possible sub, Telephony uses this new interface API to update
the phoneAcount handle to Telecomm which inturn helps to display
the proper subId on which ECall placed.
Add cause codes for EMERGENCY_TEMP_FAILURE and  EMERGENCY_TEMP_FAILURE
