Subject: [PATCH] Make fingerprint registration flow full screen

Since the fingerprint registration sometimes has a hardware dependency,
to bring a better UX, make the flow full screen on large screen devices.

Bug: 197717071
Test: Try to register a new fingerprint and see the pages are full
screen.
