Add support for WT32-ETH01 ethernet board and make ethernet support configurable (wled#1583)

* Initial support for WT32-ETH01 board

* Initial ethernet config option, doesn't save yet

* Fixed saving/restoring ethernet option, works now!

* Fixed ESP32-POE pin config (thanks to tbnobody)

* Remove esp32_eth target (use poe), minor cleanup

* Fix BTNPIN for WT32-ETH01, as found by @k7bbr

* Various fixes to ethernet option
