test: enable test-debugger-pid

[Trott]

Now that node debug is an alias for node inspect, it's possible that
node-debug-pid can run reliably. Modify for current behavior and move
from disabled to parallel.

Checklist

• make -j4 test (UNIX), or vcbuild test (Windows) passes

test debugger inspector

Labeled as in progress pending CI results as I'm not able to run on Windows etc. locally.

Hmmm...Windows fails. A few options:

• skip the test on Windows
• bifurcated logic to handle Windows behavior
• remove the test entirely as it's mostly testing the behavior of the node-inspect dependency anyway and not Node.js core itself

Thoughts? /cc @jkrems

Added code to skip parts of the test on Windows.

CI: https://ci.nodejs.org/job/node-test-pull-request/7767/

Because I hope/expect this to pass CI, I'm going to remove the in progress label too...

I think in the future we should investigate adding make test-node-inspect to our general CI runs. Until then having some smoke tests like this one as part of node's own test suite is definitely valuable.
