updates tailscale/tailscale#13937
Builds a TailscaleKit.framework which wraps libtailscale.a in an actor,
providing IncomingConnection, Listener, and OutgoingConnection
types which are more usable in pure async Swift code. The
method signatures are intended to be similar in form to NWConnection.
We also provide an extension to URLSession so you can make URL
requests via the user-space proxy.
Adds a static library mirroring much of the test control utilities in go, minus
the dependency on testing, so that we can export the signatures and
link it to tests that cannot run in go.
Added functionality to get both the local interface IPs as well as
the remote IP of incoming connections accepted by a listener.
Fixed a bug in the log writer so we append a newline.
This also updates to the latest go toolchain and tailscale version.

Use a socketpair(2) and sendmsg/recvmsg to pass a connection fd
from Go to C. This lets people write non-blocking C by polling on a
tailscale_listener for when they should tailscale_accept.
