James Tucker 76256d22d8 wgengine/router: windows: set SkipAsSource on IPv6 LL addresses
Link-local addresses on the Tailscale interface are not routable.
Ideally they would be removed, however, a concern exists that the
operating system will attempt to re-add them which would lead to
thrashing.

Setting SkipAsSource attempts to avoid production of packets using the
address as a source in any default behaviors.

Before, in powershell: `ping (hostname)` would ping the link-local
address of the Tailscale interface, and fail.
After: `ping (hostname)` now pings the link-local address on the next
highest priority metric local interface.

Fixes #4647
