feat(node): Skip patching when breadcrumbs are disabled

[chargome]

If I understood this correctly we can save some work when breadcrumbs are disabled as the only outcome here is addRequestBreadcrumb(request, response); anyway

ref #15725

Currently, yes, but this will not be true anymore wenn this: #15735 is merged. but we can still check for multiple conditions then and avoid adding the instrumentation when we know it would do nothing!
