Allow SimDialogActivity to be started for result

Allow SimDialogActivity to be started for result

In Telephony, we sometimes need to be able to launch
the SIM pick dialog activity for SMS without setting
a new default (i.e. user chose "ask every time") for
default SMS subscription.

Adds the ability for the SimDialogActivity to be
called using startActivityForResult and not set the
user's choice as the default.
