The `tools/node_compat/node` submodule has been moved to `tests/node_compat/runner/suite` and the remaining files within `tools/node_compat` to `tests/node_compat/runner`. Most of the changes are of the header within `tests/node_compat/test` files. The `setup` and `test` tasks within `tests/node_comapt` execute successfully. Towards #22525 CC @mmastrac
