IMS: Update context based switch based on the DSDA/DSDS scenario

- Context based switch will not be updated to false while exiting
  DSDA during the call. It will result in the call can't be active
  after swapping the calls.

- After receiving MSIM_VOICE_CAPABILITY_CHANGED, update context
  based switch.
