Revert "[wlan][legacy] Provide retrieval for saved network"

This reverts commit d351b2f23ac44230e9b21f2285e810563cfa81a1.

Reason for revert: breaks a private implementation of fuchsia.wlan.service.Wlan:

fidling/gen/sdk/fidl/fuchsia.wlan.service/fuchsia/wlan/service/cpp/fidl.h:323:16: note: unimplemented pure virtual method 'GetSavedNetworks' in 'FakeWlan'
  virtual void GetSavedNetworks(GetSavedNetworksCallback callback) = 0;

Original change's description:
> [wlan][legacy] Provide retrieval for saved network
> 
> Provides legacy support for retrieving saved network names.
> This feature is of temporary nature while we bring up the
> "new" API.
> 
> Test: Included
