[libpas] Parallelize test runner
https://bugs.webkit.org/show_bug.cgi?id=304285
rdar://164655522
Reviewed by Keith Miller.
With this patch, TestHarness.cpp will launch up to NCPUs/2 test
processes at once by default. This is friendlier than NCPUs for
contended cases like CI runners, while still being a big speedup
for desk usage.
This default can be overridden via the PasTestConcurrency envvar.
On my M3 Macbook Pro, this reduces the wall-clock time of `./test.sh`
from ~16m to a bit under ~5m, using `PasTestConcurrency=8`.
