REGRESSION (278619@main): [iOS] TestWebKitAPI.WKWebExtensionAPIComman…

…ds.PerformKeyCommand is timing out

Reviewed by Brian Weinstein.

Updated the unit test for performing key command for web extensions.
The key command will never be a firstResponder so it is incorrect
to try to fire the keyCommand object directly. Instead, do what
the client firstResponder would do: invoke -performCommandForKeyCommand:
on the context object.
