Align the size of pattern view in ChooseLockPattern,
ConfirmLockPattern, and keyguard as much as possible.
In rare cases they may still be inconsistent because
the screens have different content outside of the
pattern view (e.g. header text, navigation buttons etc)

Theme the confirm password screen similar to setup wizard and screen
lock enrollment flow, so that we can start showing it during setup
wizard.
The new layouts are called "internal" because it's supposed to be
used only when another settings screen starts it. For external
intents from CONFIRM_DEVICE_CREDENTIAL, the existing theme and layout
are unchanged.
