WifiConfigManagerNew: Set |hasEverConnected| flag

1. Migrate the existing |wasCredential| change method in
|WifiConfigManager| to |WifiConfigurationUtil|.
2. Integrate this into the |WifiConfigManagerNew|.
3. Move/Refactor the |hasIpChanged| & |hasProxyChanged| helper
methods to |WifiConfigurationUtil| as well.

While there,
Change couple of occurences of {@code true} to |true| in javadocs to be
consistent across the class.
