        Cache memory object size in WebCLMemoryObjects.

        Issue #398

        Reviewed by Antonio.

        The size memory objects like buffer & images needs to be
        cached identical to WebGL. This can be used for verification
        & validation in enqueue API's to avoid bad memory access.

        No new tests (OOPS!).
