POSIX specifies that functions like `nanosleep` use the REALTIME clock, so allow WASI `poll_oneoff` calls to use the REALTIME clock, at least for non-absolute intervals. POSIX specifies that the timeouts should not be affected by subsequent `clock_settime` calls, so they behave the same way as MONOTONIC clock requests, so we can implement them as monotonic requests.
