fix#7947
move `BasicHost.AutoNat` to a private field (it has no public method and shouldn't be accessed afaik.
Instead add a setter for config that sets it while holding the address mutex to prevent reads of the
field at the same time.
Currently, the AutoNAT dialer spins up a full host with identify, ping, etc.
this switches to a blankhost.
This also avoids running a relay, listening on transports, etc (regression).
