weak hook preinit() #2111 #2133 #2136 (#5395)

Browse Source 
* weak hook early_setup() #2111 #2133 #2136

* rename to early_init (more "c" vs early_setup which is more "c++arduino")

* example

* improve earlyWiFi example, slightly change AddrList interface, move WiFi sketches into WiFi examples

* fix CI

* fix local CI runner

* fix local CI runner

* rename early_init() to preinit()

* + static ESP8266WiFiClass::preinit_wifi_off()

* update early disable wifi example

* example update

* IPv6 example update

* Update ESP8266WiFiGeneric.h

camelCase for static method name

* Update ESP8266WiFiGeneric.cpp

camelCase for static method name

* Update EarlyDisableWiFi.ino

Expand comment, fix static method name
