Therefore, we move the related resource to SettingsLib to share the usage. Bug: 242326166 Test: make RunSettingsRoboTests ROBOTEST_FILTER=FontSizeDataTest Test: Maually test the availability of changing font size through Settings page Change-Id: Ia2621e3b4c71f900e6591644d0e3f93bedbe4ee8 Merged-In: If630bd9c9c27823c210410b53342b921a11bbfb9
