Make SettingsProvider able to restoreAnyVersion, but only
for supported keys

RestoreAnyVersion is supported only for K/V, as full backup
of SettingsProvider has been deprecated (b/71746093).
The supported keys whitelist only contains KEY_WIFI_NEW_CONFIG
and KEY_NETWORK_POLICIES for now, and will be extended in future CLs.
