Making "Battery Saver" use MasterSwitchPreference.
By using MasterSwitchPreference, we make "battery saver" to have two parts: left part is the clickable summary jumping to other fragment while right part is a switch toggle. Also remove the previous battery saver preference. Bug: 34279051 Test: RunSettingsRoboTests Change-Id: If36fa9741e413a9bbdd57fa67a2c15b6e457afd7
