This is a continuation on the topic of adding IPv6 Support to ESP32 A…

…rduino (#9016)

* IPv6 for Arduino 3.0.0

* Fix warning in WifiUdp

* remove comment / formating

* Add zone to IPAddress and update WiFiUDP and WiFiGeneric

* Add from ip_addr_t conversion and better toString implementation

* Use constant for IPAddress offset

@sgryphon is this better?

* Combine hostByName to support both IPv6 and IPv4 results

* implement logic to use v6 dns only when global v6 address is assigned and remove IPv6Address

* Rename softAPenableIPv6

* Rename mDNS methods

* fix IPAddress method to work with const address

* Some cleanup and do not print zone in IPAddress

* rename WiFiMulti method

* Fix AP DHCPS not properly working on recent IDF

* Add option to print the zone at the end of IPv6

@TD-er

* remove log prints from hostByName

* Use correct array length for listing IPv6 addresses

* Implement some Tasmota requirements

Added constructor that takes `const ip_addr_t *`.
Added `addr_type()` getter
Organize header to highlight the Espressif additions to IPAddress

* add 'const' to IPAddress::addr_type()

* Fix WiFiUdp not updating mapped v4 address

* Update WiFiServer.cpp
