Add checkbox for erase esim under network reset screen

This CL add a checkbox letting user decide when they reset the network
configurations under System > Reset options > Reset Wi-Fi, mobile &
Bluetooth, whether they want to reset eSIM together or not. If the user
choose to reset eSIM togather, EuiccManager#eraseSubscriptions will be
called and all the eSIM profiles will be removed.
