        Don't send zeros in TexImage if GL implementation handles that
        https://bugs.webkit.org/show_bug.cgi?id=60581

        Chromium already handles zeroing textures upon creation, so don't
        bother zeroing them in WebKit, as that causes some unnecessary memcpys
        of zeros.

        No new tests as functionality is the same.
