Automatic update from web-platform-tests
[top-level await] Prohibit top-level await in service workers

This CL disallows top-level await for service workers by
terminating the worker.

The error that's thrown when Run Service Worker fails is changed
to a TypeError per the spec draft for top-level await integration [0].

Note that this also changes the sudden termination errors that were
previously AbortErrors to TypeErrors.
