Move this down so the constants stay in alphabetical order?

I debated that, but I opted to have them side-by-side; FWIW this list is already
not quite alphabetically sorted (i.e. kSupervisedUserSettingsFilename).

I don't really care, if you feel strongly I'll make the change; it just felt
like having kPref.., kDeprecatedProtectedPref.., and kSecurePref.. together was
easier to read.

I do prefer alphabetic.

The kSupervisedUserSettingsFilename is an artifact of a recent renaming, which
I'm about to fix :)

Done (and changed kDeprecatedProtectedPreferencesFilename to
kProtectedPreferencesFilenameDeprecated so that it at least doesn't end up alone
at the top).
