Wallet/controls - Migrate existing settings

Step 2 of 2. Move wallet settings from System -> Gestures -> Power
Menu to Display -> Lockscreen. Split the existing sensitivity setting
into two separate toggles to give users better control of their
privacy settings.

Bug: 185597511
Test: make RunSettingsRoboTests -j ROBOTEST_FILTER=com.android.settings.display
