James Tucker 5c2b2fa1f8 ipn/ipnlocal: plumb ExitNodeDNSResolvers for IsWireGuardOnly exit nodes
Control sends ExitNodeDNSResolvers when configured for IsWireGuardOnly
nodes that are to be used as the default resolver with a lower
precedence than split DNS, and a lower precedence than "Override local
DNS", but otherwise before local DNS is used when the exit node is in
use.

Neither of the below changes were problematic, but appeared so alongside
a number of other client and external changes. See tailscale/corp#14809.
