Reset telephony stack during Reset Mobile Network flow

This CL introduces two more steps to restart Phone process and RILD
during the Reset mobile network flow by the help of the
TelephonyContentProvider which has been used by Pixel Adaptive
Connectivity Services ("SCONE") for a while.

The additional reset options can resolve issues like resources leak
and internal state stuck, effectively recover telephony stack into
fresh state.

The reset options are performed in the background and have no impact
on UX of the reset flow.
