Updating EndpointSliceCache sort function to be significantly faster.

Browse Source 
The .IP() call that was previously used for sorting resulted in a call
to netutil to parse an IP out of an IP:Port string. This was very slow
and resulted in this sort taking up ~50% of total CPU util for
kube-proxy.
