feat(coverage): v8 to track node:child_process and node:worker_threads contexts

[AriPerkkio]

Description

• Fixes coverage not collected from sub-propcesses result from child_process APIs #7064
• Fixes How to get code coverage for scripts called as worker process/thread? #3851
• Fixes Vitest coverage for workerthread files #9842
• Also related to @vitest/web-worker error when using browser environment #4899

Users will likely run into nodejs/node#62301 when testing node:worker_threads. We'll need to document that.
