Chromium has local storage enabled in icognito windows, and simply doesn't
persist it to disk. QtWebEngine seems to do the same when local storage is
enabled in an off-the-record profile, so there's no reason to disable it by
default.

This also matches the behavior in Chromium (and Firefox, but not Safari).

[ChangeLog] HTML 5 local storage is now enabled by default (but residing in
memory) in off-the-record profiles.
