Implement SIM swapping

When the call is still ringing, a new button is added to allow to user to call with the other SIM. A background worker will be created to hang up the phone and redial with the other SIM. The in call UI will be prevented from ending during the process.

 UX has not been finalized, the icon and position are just placeholder.
