REGRESSION(256008@main) TestWebKitAPI.IPCTestingAPI.CanIntercept* tes…

…ts fail https://bugs.webkit.org/show_bug.cgi?id=247256 rdar://problem/101749810 Reviewed by Ryosuke Niwa. The commit 256008@main changed the encoding for messages that have async replies: - Before, the reply id was encoded as the first parameter. - After, the reply id was encoded as the last parameter. This broke the JS IPC tester API where message listener code was not adjusted accordingly. This caused the arguments to be decoded incorrectly. Fix the JS IPC tester API. Add a test testing that listener API can be used to obtain the async reply id. * LayoutTests/ipc/message-listener-async-message-reply-id-expected.txt: Added. * LayoutTests/ipc/message-listener-async-message-reply-id.html: Added.
