chore: move tools/node_compat to tests/node_compat/runner (#23025)
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
