These tunings reduced memory usage while the implementation was
struggling with earlier bugs, but will no longer be necessary after
those bugs are addressed.

cmd/natc,wgengine/netstack: tune buffer size and segment lifetime in natc
...
Some natc instances have been observed with excessive memory growth,
dominant in gvisor buffers. It is likely that the connection buffers are
sticking around for too long due to the default long segment time, and
uptuned buffer size applied by default in wgengine/netstack. Apply
configurations in natc specifically which are a better match for the
natc use case, most notably a 5s maximum segment lifetime.

cmd/natc: initial implementation of a NAT based connector
...
This adds a new prototype `cmd/natc` which can be used
to expose a services/domains to the tailnet.
It requires the user to specify a set of IPv4 prefixes
from the CGNAT range. It advertises these as normal subnet
routes. It listens for DNS on the first IP of the first range
provided to it.
When it gets a DNS query it allocates an IP for that domain
from the v4 range. Subsequent connections to the assigned IP
are then tcp proxied to the domain.
It is marked as a WIP prototype and requires the use of the
`TAILSCALE_USE_WIP_CODE` env var.
