This change deprecates CONFIG_POSIX_MQUEUE in favour of
CONFIG_POSIX_MESSAGE_PASSING, which maps directly to the name of the
standard POSIX Option.

The POSIX_CLOCK option does not correspond to any standard
option. It was used to active features of several distinct
POSIX Options and Option Groups, which complicated API and
application configuration as a result.
POSIX_CLOCK is being deprecated in order to ensure that Zephyr's
POSIX Kconfig variables correspond to those defined in the
specification, as of IEEE 1003.1-2017.
Additionally, CONFIG_TIMER is being deprecated because it does
not match the corresponding POSIX Option (_POSIX_TIMERS).
With this deprecation, we introduce the following Kconfig
options that map directly to standard POSIX Option Groups by
simply removing "CONFIG_":
* CONFIG_POSIX_TIMERS
Similarly, we introduce the following Kconfig options that
map directly to standard POSIX Options by simply removing
"CONFIG":
* CONFIG_POSIX_CLOCK_SELECTION
* CONFIG_POSIX_CPUTIME
* CONFIG_POSIX_DELAYTIMER_MAX
* CONFIG_POSIX_MONOTONIC_CLOCK
* CONFIG_POSIX_TIMEOUTS
* CONFIG_POSIX_TIMER_MAX
In order to maintain parity with the current feature set, we
introduce the following Kconfig options that map directly to
standard POSIX Option Groups by simply removing "CONFIG_":
* CONFIG_POSIX_MULTI_PROCESS - sleep()
Similarly, in order to maintain parity with the current feature
set, we introduce the following additional Kconfig options that
map directly to standard POSIX Options by simply removing
"CONFIG":
* CONFIG_XSI_SINGLE_PROCESS - gettimeofday()

Update prj.conf so that
subsys/net/lib/sockets/socketpair.c
is pulled into the build and zsock_socketpair() is
properly defined.

Add a trivial suite that simply ensures headers exist and that
they supply standard symbols and constants.
These tests are intended to be ordered exactly as the respective
feature appears in the respective specification at
https://pubs.opengroup.org/onlinepubs/9699919799
Over time, as POSIX support improves, we can enable additional
checks.
If `CONFIG_POSIX_API=n`, then we simply ensure that the header
can be included, that constants and structures exist, including
the existence of required fields in each structure.
We check that a constant exist, by comparing its value against
an arbitrary number. If the constant does not exist, it would
of course be a compile error.
```
zassert_not_equal(-1, POLLIN);
```
We check that a structure contains required fields by
comparing the field offset with an arbitrary number. If
the field does not exist, of course, there would be a
compile error.
```
zassert_not_equal(-1, offsetof(struct pollfd, fd));
```
For non-scalar constants, we simply attempt to assign
a value to the specific type:
```
struct in6_addr any6 = IN6ADDR_ANY_INIT;
```
If `CONFIG_POSIX_API=y`, then we additionally check that required
functions are non-NULL (limited to what is currently supported in
Zephyr).
```
zassert_not_null(pthread_create);
```
Note: functional verification tests should be done outside of this
test suite.
