mtest: move determine_worker_count to utils, generalize
It is useful to apply a limit to the number of processes even outside "meson test",
and specifically for clang tools. In preparation for this, generalize
determine_worker_count() to accept a variable MESON_NUM_PROCESSES instead of
MESON_TESTTHREADS, and use it throughout instead of multiprocessing.cpu_count().
