[Biometric Onboarding & Edu] Support ways to use section for Face & FP

Move "Ways to use" section from "Face & Fingerprint Unlock" page to
"Face unlock" & "Fingerprint unlock" pages which means Face &
Fingerprint settings now have their own "Unlock your phone" & "Verify
it's your in app" settings.
