Add setting page for swipe to notification.

In this change input & gesture page added 5 separate gesture
preferences, each should lead to a new page to set gesture setting. For
now only swipe to notification preference is wired up. Will implement
the rest in later changes.

Bug: 32637613
Test: make RunSettingsRoboTests -j40
