[BREAKING] Disable WiFi at boot by default (#7902)

Browse Source 
* Disable WiFi at boot by default

* +define WIFI_IS_OFF_AT_BOOT

* remove now useless example

* mv enableWiFiAtBootTime() to core_esp8266_features.h

* sync with master

* per @earlephilhower review: a file was missing

* doc

* WiFi persistence is now false by default

* fix doc

* ditto

* doc: remove sphinx warnings (fix links and formatting)

* fix link name

* fix doc

* legacy: restore persistence

* undeprecate preinit()

* move force modem up to when mode has changed (per @mcspr review)

* do not wake up from sleep when mode if OFF

* fix doc per review
