feat(net): Switch to typedefs for WiFiClient, WiFiServer, WiFiUdp and WiFiClientSecure (#9909)

* feat(net): Deprecate old WiFi APIs

Deprecates WiFiClient, WiFiServer, WiFiUdp and WiFiClientSecure

* fix(net): add defines to WiFi.h

Defines are added to not cause deprecation warnings. Will be removed in the future

* fix(net): Use typedefs instead to help with forward declarations

Defines do not allow forward declarations
