        [Chromium][DRT] WebTask should use webkit_support::TaskAdaptor
        https://bugs.webkit.org/show_bug.cgi?id=55434

        Changed WebTask to be a subclass of webkit_support::TaskAdaptor
        and passed the object webkit_support::PostDelayedTask directly.

        Note that the change keeps postTask() as is because it has a
        semantics taht webkit_support::PostDelayedTask() has; It jumps to
        the main thread.
