Have a new library - netd-client in frameworks/libs/net

Move BaseNetdUnsolicitedEventListener from tethering module to
frameworks/libs/net and have a new library for it.
Tethering module can still use BaseNetdUnsolicitedEventListener
through netd-client and ConnectivityService and Nat464Xlat also
can use it when both of them are under frameworks/base.

Bug: 174837473
