posix: reword aio and sched options. add experimental
The asynchronous I/O and (process) scheduling options needed
minor rewording.
Additionally, add the experimental flag to each of them since
they are not yet supported.

Enable this option for asynchronous I/O. This option is present for conformance purposes
only. All functions listed in <aio.h> return -1 and set errno to ENOSYS.

This enables POSIX scheduling APIs (_POSIX_PRIORITY_SCHEDULING).

+ Since Zephyr does not yet support processes, most of this behaviour is undefined, except for
+ use of sched_get_priority_min() and sched_get_priority_max().
