[Backport] CVE-2023-2134: Out of bounds memory access in Service Worker API

Cherry-pick of patch originally reviewed on
https://chromium-review.googlesource.com/c/chromium/src/+/4406580:
Stop supporting { handleEvent }.

M108 merge issues:
  content_unittests_bundle_data.filelist:
    Not present in 108, skipped; Only used in iOS tests on main

Make the code aligned with the following specification update:
https://github.com/w3c/ServiceWorker/pull/1676

With the previous specification and code, event listener vector
can be modified during the GetEffectiveFunction execution, which may
bring unexpected vector state.

(cherry picked from commit 5105ce37a6853d52ec97894bf6969b3c29a23afd)
