mtest: remove usage of executors
Rewrite the SingleTestRunner to use asyncio to manage subprocesses,
while still using subprocess.Popen to run them. Concurrency is
managed with an asyncio Semaphore; for simplicity (since this is
a temporary state) we create a new thread for each test that is run
instead of having a pool.
This already provides the main advantage of asyncio, which is better
control on cancellation; with the current code, KeyboardInterrupt
was never handled by the thread executor so the code that tried to handle
it in SingleTestRunner only worked for non-parallel tests. And
because executor futures cannot be cancelled, there was no way for
the user to kill a test that got stuck. Instead, without executors
^C exits "meson test" immediately. The next patch will improve things
even further, allowing a single test to be interrupted with ^C.
