Add the new app permission screen.

This screen allows toggling the permission (either dual- or tri-state)
and will eventually show the permission justification.  It will also
replace PermissionPreference, from which most of the logic is copied.

This modifies PermissionUsagePreference so that clicks go to this page
instead of the old PermissionPreference pages.

Bug: 63532550
Bug: 118437704
Test: Used the new screen to toggle permissions.
Test: Manually forced the code down the paths of the rare conditions.
