updates tailscale/tailscale#13937
This adds localAPI support into TailscaleKit. LocalAPI can now be queried
via the SOCK5 proxy on both MacOS and iOS. This also fixes SOCKS5
support for iOS so you can simply apply our config to a URLSession.
This pulls in most of LocalAPI - though much of it is untested, it's based
on the implementation in tailscale/corp/xcode.
Unit tests pending.
