tempfork/wireguard-windows/firewall: add.

This is a fork of wireguard-windows's firewall package, with
the firewall rules adjusted to better line up with tailscale's
needs.

The package was taken from commit 3cc76ed5f222ec82748ef3bd8c41d4b059e28cdb
in our fork of wireguard-go.

This is a copy of the `tunnel/firewall` package of
https://git.zx2c4.com/wireguard-windows, with some hardcoded filter
rules adjusted to function with Tailscale, rather than
wireguard-windows's process structure.
You should not use this package. It exists as a band-aid while we
figure out how to upstream a more flexible firewall package that does
the fancier things we need, while also supporting wireguard-windows's
goals.
