Fixes#23865, Fixes ENG-21446
Previously, a termination exception would be thrown. We didn't handle it
properly and eventually it got caught by a `catch @panic()` handler.
Now, no termination exception is thrown.
```
drainMicrotasksWithGlobal calls JSC__JSGlobalObject__drainMicrotasks
JSC__JSGlobalObject__drainMicrotasks returns m_terminationException
-> drainMicrotasksWithGlobal
-> event_loop.zig:exit, which catches the error and discards it
-> ...
```
For workers, we will need to handle termination exceptions in this
codepath.
~~Previously, it would see the exception, call
reportUncaughtExceptoinAtEventLoop, but the exception would still
survive and return out from the catch scope. You're not supposed to
still have an exception signaled at the exit of a catch scope. Exception
checker may not have caught it because maybe the branch wasn't taken.~~
