This commit adds unit tests for the SO_REUSEADDR socket option to test
the different possible scenarios for the option to work correctly.
There is also a fix for the TCP testsuite to make a now failing test
pass again due to a TIME_WAIT socket.

For some reason, tests/net/socket/tcp/net.socket.tcp.preempt
was failing to link for vmu_rt1170 with these changes, and
for some reason reducing CONFIG_POSIX_MAX_FDS from 20 to 10
resolves that issue.

Add an `after()` function that is executed after each test in
the testsuite.
Previously, even if one one test failed, it would calls almost
all subsequent tests to fail. This way, other tests can still
succeed.

After several fixes of the re-ordering logic in TCP, the receive queue
works as intended and cleans itself up properly. Previously the default
timeout was 100 ms, which pretty much disables it for real applications.
Increase the timeout to 2 seconds to actually enable it for in practice.
This should help pass much more of the Maxwell Pro tests.
This is the first step before removing the timeout completely.

Instead of waiting for the retransmit timeout, retransmit as soon as
missing data is deduced based on a triple-duplicate ACK.
Increase the number of buffers in the testcase, to allow for at least 4
packets in flight to trigger the triple-duplicate ACK.

It can happen that two similar stacks enter a retransmission cycle
due to a packet collision. If the transmission timeout is the same
both stacks will retry at the same moment resulting in another
collision.
By introducing a randomized retry timeout, the chance of
a second collision is reduced and it reduces furter the more
retransmissions occur.

Apply an exponentially increasing wait time between tcp retries. This
is a good balance between reacting fast to single lost packets and reduce
the network load when an outage takes a little longer. It also allows the
connection to survive a longer interruption with less retransmissions.
Update the test to accommodate for the increased socket closure timeout

Previously the test waited for the worst case time till all sockets
where closed, this causes the test to wait for a long unnecessary time.
Secondly it does not ensure the sockets are actually closed before
starting the next tests.
For tests that are not conducted in user mode, wait until all the contexts
are close for a maximum time. If the contexts are not closed in time raise
an explicit assertion.

The close function on a TCP socket can return before the complete
socket has been closed, as there might be packets still in flight.
Add a wait at the end of the test so we are sure all sockets have
been closed before the next test starts.

The close function on a TCP socket can return before the complete
socket has been closed, as there might be packets still in flight.
Modify the test to wait briefly (less then the retransmit time), before
counting the number of still open net_contexts. This makes the test
outcome not dependent on the scheduling order of the different tasks.
Secondly the test actually checks the number of open contexts to be zero
so there is no need to wait for any open contexts to still close.

A common pattern here was to take the work item as the subfield of a
containing object. But the contained field is not a k_work, it's a
k_work_delayable.
Things were working only because the work field was first, so the
pointers had the same value. Do things right and fix things to
produce correct code if/when that field ever moves within delayable.

Fixes: #38403
Adding NET_DRIVERS menuconfig so that network drivers are grouped
together in its own menu entry under drivers, similar to most other
drivers.
This further has the advantages that `CONFIG_NET_DRIVERS` can be used
for testing to determine if network drivers has been selected.
This changed revealed a dependency loop where both `select` (for SLIP)
and `depends` (for PPP) which both depends on NET_DRIVERS` where in use
in the dependency tree for Qemu networking, especially NET_SLIP_TAP.
This is handled by defaulting `NET_DRIVERS` to `y` when building for a
Qemu target.
`SLIP` had a dependency to `!QEMU_TARGET || NET_QEMU_SLIP`. This is
changed so that SLIP prompt depends on `!QEMU_TARGET` which provides
full user control in hardware but makes the symbol promptless on Qemu
targets.

At the Toolchain WG it was decided to move to CMake 3.20.0.
The main reason for increasing CMake version is better toolchain
