rtio: Enable submit/consume semaphores by default 

The default behavior for thread pending of completions should use
semaphores rather than yield/wait looping when multithreading is
available.

Disable by default only when multithreading isn't available.

When calling rtio_submit a semaphore is available to sleep the calling
thread for each completion queue event until the wait count is met. This
adds a small RAM overhead for a single semaphore. By default wait_for will
use polling on the completion queue with a k_yield() in between iterations.
