Files in `node_modules` are not authored by the user directly and the original sources are less relevant to the user. Skipping source maps in `node_modules` improves the general performance. Add `module.setSourceMapsSupport(enabled, options)` to skip source maps in `node_modules` if it is needed. This moves all source maps related API to `node:module` and this a step to promote the source maps API to stable.
