JSON Config Schema Generator #216

Re nodejs/node#57016 nodejs/node#57171

There is a new generator for node.config.json schema. The doc tooling just calls an internal function and writes what it returns to a file. The internal function (generateJsonSchema) could be moved into a new generator here.

However, it's worth noting that that function calls a native function (getEnvOptionsInputType) that does need to stay in Node core.
