* fix: add patch to avoid crash in worker with nodeintegration enabled [worker_global_scope.cc(111)] Check failed: url_.IsValid(). * fix: loading dedicated/shared worker over custom protocols Backports https://chromium-review.googlesource.com/c/chromium/src/+/1798250 that distinguishes loading the main script resource of dedicated/shared worker, this allows us to register a custom URLLoaderFactory. * spec: add crash test for worker with nodeIntegrationInWorker * update patches * Remove extra patchlist patches * Fixup patch * update patches Co-authored-by: deepak1556 <hop2deep@gmail.com> Co-authored-by: Shelley Vohr <shelley.vohr@gmail.com> Co-authored-by: Electron Bot <anonymous@electronjs.org>
