Subject: test(ext/node): more node compat tests (#17827)

This PR adds the remaining ~650 Node.js compat test cases from std/node.

Among these 650 cases, about 130 cases are now failing. These failing
cases are prefixed with `TODO:` in `tests/node_compat/config.json`.
These will be addressed in later PRs.
