graphviz package: add MacOS fixes and quartz support (#11128)

* Add patch to detect newer versions of MacOS and to fix a typo in
  configure.ac (AM_LIBTOOLSFLAGS should be AM_LIBTOOLFLAGS)
* Remove variant declarations for unsupported languages
* Add support for quartz on MacOS
* Add optional X Window support
* Specifically build against qt@4 when building QT support
* Point to appropriate C++ standard libraries when building with
  Clang on MacOS
* Disable parallel build (for all platforms)
* Increase verbosity of configure script by adding
  --disable-silent-rules
