The infinite loop during the stress needs to be broken
with a small delay when built for native targets.
Let's add it.
Note that this delay is only added for ARCH_POSIX targets
and not any other.

The test case allocate struct k_thread thread in the stack. This will
lead the random initial value of thread and thus cause the test cases
randomly hang. To fix such issue, move the declartion of struct k_thread
thread outside the function as a stacic variable.

Make sure that `poll(..., POLLIN)` executed from another thread returns
when `eventfd_write()` is called. Test also the same with `poll(...,
POLLOUT)` and `eventfd_read()` on eventfd with counter equal to
`UINT64_MAX - 1`.

This test simply counts how many times `eventfd_read()`
and `eventfd_write()` can be called on an
`eventfd(0, EFD_SEMAPHORE | EFD_NONBLOCK)` file
descriptor.
Prior to the recent changes in `eventfd`, we were seeing
approximately < 1000 writes / s. However, the previous
`eventfd` implementation would fail this test with the
result that the number of successful reads was far greater
than the number of successful writes.
This should be impossible, and with the recent `eventfd`
changes that was fixed. Additionally, we are seeing an
increase in over 40x for non-blocking eventfd reads and
writes.

Previously, the prototypical use case for `eventfd()` was not
possible in Zephyr due to a deadlock associated with the
`fdtable.c` `k_mutex`.
The prototypical use case for `eventfd()` is to make a
blocking call to `eventfd_read()` from one thread, and then
from another thread, call `eventfd_write()` to "wake up" the
reading thread.
This additional test case ensures that Zephyr supports the
prototypical `eventfd()` use case.

Move to CMake 3.20.0.
At the Toolchain WG it was decided to move to CMake 3.20.0.
The main reason for increasing CMake version is better toolchain
support.
Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20

When there were multiple writes to eventfd, then poll() + read() should
start behaving as just initialized. Test that by verifying poll() will
timeout first and later be notified properly when eventfd is written
once again from the other thread.

Test is configured with CONFIG_POSIX_API=y, so there is no reason to
check for it being enabled in C. Additionally when CONFIG_POSIX_API=n a
much "bigger" posix/sys/socket.h was included instead of net/socket.h,
which should be rather opposite.

This implements a file descriptor used for event notification that
behaves like the eventfd in Linux.
The eventfd supports nonblocking operation by setting the EFD_NONBLOCK
flag and semaphore operation by settings the EFD_SEMAPHORE flag.
The major use case for this is when using poll() and the sockets that
you poll are dynamic. When a new socket needs to be added to the poll,
there must be some way to wake the thread and update the pollfds before
calling poll again. One way to solve it is to have a timeout set in the
poll call and only update the pollfds during a timeout but that is not
a very nice solution. By instead including an eventfd in the pollfds,
it is possible to wake the polling thread by simply writing to the
eventfd.
