[bindings] Use |PostMessage| attribute for CrossOriginServiceWorkerClient.postMessage to eliminate custom bindings

The CL [1] has introduced |PostMessage| IDL extended attribute to auto-generate the code required for interfaces
using |postMessage| method. In doing so, the bindings template generator uses |interface_name| while creating
the ExceptionState object here [2]. In this case, |CrossOriginServiceWorkerClient| name will be used instead of
|ServiceWorkerClient|.
