Move to using new public accessors on DiskInfo and VolumeInfo.
Persist nickname changes, and remember when user has initialized a
public volume. Also skip the migration part of storage wizard until
it's implemented.

Use frameworks/opt/setupwizard/library/ for consistent behavior and
styling on phones and tablets. Implement every step of wizard flow
and connect them together, even though some steps are currently
non-functional. All strings to match UX spec, with some adjustment.
Wizards inherit from helper base class.
New interstitials before unmounting or formatting private storage
to confirm user knows consequences.
