  -----------
  [lld] Add test suite mode for running LLD main twice

LLD_IN_TEST determines how many times each port's `main` function is
run in each LLD process, and setting LLD_IN_TEST=2 (or higher) is useful
for checking if we're cleaning up and resetting global state correctly.
Add a test suite parameter to enable this easily. There's work in
progress to remove global state (e.g. D108850), but this seems useful in
the interim.
