The pthread_pressure test was not a typical test per se. It was a benchmark in search of the proper home. Let's move it to the correct place in the Zephyr tree, add a doc, and provide some reporting. Currently, k_threads out-perform pthreads by almost a factor of 2. The theoretical maximum performance of pthreads would be at parity of k_threads, since pthreads are a wrapper around kernel threads. It would be great to reduce the gap. Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
