ref(node-core): Add more specific mechanism.type to worker thread errors from childProcessIntegration (#17578)

Sets a more specific mechanism type. The main problem here is that I
didn't find a suiting category to be used with trace origin. So I
decided to go with a similar format but the category doesn't match an
existing cat.
