Add Pico W WiFi support (#670)
* Add support for the WiFi chip on the Pico W board.
* USB interrupt now no longer hard coded (conflicted with the WiFi IRQ).
* Add in Pico W board to makeboards.py
* Add in GPIO and variant support
* Initialize WiFi in the Variant
* Use manual LWIP, fix size accounting
* Remove the SDK WiFi overrides
* Pulling in work done in the ESP8266 core.
* Make IPAddress support IPv6
* Build LWIP with IPv4 and IPv6 support
* Use proper MAC
* Avoid cyw_warn crash.  Make macro to a comment while building
* Add WiFiServer
* Add WiFiUdp
* Move LWIP-specific support files to LWIP_Ethernet
* Add WiFi::ping (ICMP ping)
* Move ICMP echo (ping) to LWIPIntfDev
* Move hostByName to LwipIntfDev
* Add AP mode with simple DHCP server
* Add some examples and basic ESP8266 compat hacks
* Update Adafruit TinyUSB to fix crash
* Set DHCP hostname
* Make Wifi.begin() return CONNECTED with link + IP
* Return connected() on WiFi::begin
* Fix spurious TCP retransmission
* Protect LWIP from reentrancy

The Pico SDK calls "sys_check_timeouts() from inside a periodic interrupt.
This appears unsafe, as the interrupt could happen while already in the
(non-reentrant) LWIP code.

Block the interrupt from calling sys_check_timeouts by using a global flag
manually set via an RAII recursive lock.

Add interrupt protection macros around critical sections inside LWIP via
the standard defines.

These two changes should make LWIP significantly more stable and long
running.

* Support disconnecting and reconnecting WiFi
* Add WiFiServer simple example
* Update documentation

Fixes #666
Fixed #665
