Do not reset net_context information in net_app_close. In case of
TCP behind the curtains connection might wait for some timers to
expire and send some messages (e.g. ACK). If we set source port to
'0', unexpected behaviour might happen with peer connection.
Only reset net_app context related information on net_app_close.
Let net_context_put will take care of proper connection closure.

Right now in FIN_WAIT1 state, if we receive FIN+ACK message, then
tcp state changed to FIN_WAIT2 on ACK flag and immediately on FIN
flag state changed to TIME_WAIT. Then final ACK is prepared and sent
(in queue at-least) to peer. Again immediately state changed to
TCP_CLOSED, where context is freed. net_context_put frees context
and releases tcp connection. Final ACK packet which is in queue
is dropped.
As a side effect of freed ACK packet, peer device keep on sending
FIN+ACK messages (that's why we see a lot of "TCP spurious
retransimission" messages in wireshark). As a result
of context free (respective connection handler also removed), we see
lot of packets dropped at connection input handler and replying with
ICMP error messages (destination unreachable).
To fix this issue, timewait timer support is required. When tcp
connection state changed to TIMEWAIT state, it should wait until
TIMEWAIT_TIMETOUT before changing state to TCP_CLOSED. It's
appropriate to close the tcp connection after timewait timer expiry.
Note: Right now timeout value is constant (250ms). But it should
be 2 * MSL (Maximum segment lifetime).

fin_timer will be started after sending FIN to peer. After successful
reception of FIN+ACK message in FIN_WAIT1 state, fin_timer should be
cancelled.

Using the '\$' technique to accept make variables corrupts Ninja build
systems, so avoid using it when generating Ninja files. Not using it
with Ninja means we need to come up with some other mechanism to
support build-time configuration of the QEMU CLI with Ninja.

Of these, only struct net_ipv6_nbr_data::send_ns is a descriptive
change:
send_ns is used for timing Neighbor Solicitations in general, not
just for DAD.
The rest are typo/grammar fixes.

Add implementation to consider differing Rx chain delays for
S2 and S8 Coded PHY PDU reception. These changes are
required to meet tIFS timings for transmission after a
reception on S8 coding.

Remove build_only and add harness type needed for the sample/test to
allow running with sanitycheck and on devices once we have harness
support.

Still need a better way to filter and a better way to support multiple
platforms with these tests, but for now we remove the build_only tag and
make it depend on real HW.

This is just a build test, so make it part of the overall build test
instead of having a special test case for it.

Update board definitions with supported feature. This is temporary
until we have full coverage for device drivers in DTS, then we can use
DTS instead.
