Add Ethernet RAK13800 support to RAK11310

[beegee-tokyo]

Cleanup pins_arduino.h of RAK11310
Add Ethernet capability to variant.h of RAK11310
Add RAK11310/RAK13800 support to ethClient.cpp

Add RAK11310 variant to platformio.ini.
Requires long file name support on Windows 11 and git ==> Filename too long in Git for Windows

Open a PowerShell window/console, and run the following:

• Setting Registry Value:

# Check LongPathsEnabled settings
Get-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem -Name LongPathsEnabled

# If 0, set it to 1 - This is a System wide configuration
# This will fail if you do not have Admin priveleges
# Changes to CurrentControlSet\Control take effect after a system restart
$MyPSexe = Get-Process -PID $PID | % Path
Start-Process -Verb RunAs $MyPSexe "-c","Set-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem -Name LongPathsEnabled -Type DWord -Value 1"

Setting git config --system - System wide for all Windows users:

Start-Process -Verb RunAs "git" "config","--system","core.longpaths","true"
& git config "--global" core.longpaths true

Thanks for the pointers to the windows changes. This is neccessary for every rp2040 based build. I'll add this to the developer documentation.

EDIT: nevermind, it was already there...

You're welcome.
Stumbled over this before when I started using earls' repo.
