New feature “Text and reading options” for SetupWizard, Wallpaper, and Settings (16/n).

- Add the entry to "Anything else?" screen
1) Add the new activity-alias tag ".TextReadingForSetupWizardActivity", including the fragment class, action, and targetActivity.
2) Temporarily use the “DISPLAY_SETTINGS” category to trigger “.TextReadingForSetupWizardActivity” to ensure the backward compatibility.
3) Add the text reading settings page entry into SettingsGateway to be successfully launched from SuW.
