Look for symbol node_register_module_v${NODE_MODULE_VERSION} if the
add-on didn't self-register. This can be used to create add-ons that
support multiple Node.js versions from a single shared object.

An experiment to make add-on loading more flexible. Can be extended to n-api, cc @nodejs/n-api.

Longer term, I'd like to get rid of the __attribute__((constructor)) approach. It's convoluted and complicated for no good reason.

Small fix-up to make the test export the symbol on Windows: https://ci.nodejs.org/job/node-test-pull-request/13401/

Move some code around and clean up the DLib helper class as prep work
for a follow-up commit.
