Add `module.entrypoint`, a property exposing the resolved URL of the entry point of the current thread. Unlike `require.main`, it works regardless of whether the entry point is a CommonJS or an ECMAScript module, and inside worker threads it reflects the entry point of the worker itself, matching the semantics of `require.main` and `import.meta.main`.

module.entrypointtonode:module: the resolved URL string of the entry point of the current thread.The semantics follow
require.mainandimport.meta.main(thread-scoped): inside a worker thread it is the URL of the script the worker was started with, not the entry point of the process. This complements #64800, which exposes the process-wide entry point inherited by workers.undefinedfor--eval, the REPL, STDIN input, andeval: trueworkers; set to thedata:URL for data URL workers.--preserve-symlinks-main), so it matchesrequire.main.filename/ the entry point'simport.meta.urlrather thanprocess.argv[1].Refs: #51840
