Move VTK and VisItBridge forward to fix Chombo reader issues.
Chombo reader was not producing proper AMR when opening files that also had particles. It was producing multi-block instead and missing blanking. Changed so that when loading only AMR meshes, the reader produces AMR. Also removed the Enzo reader as it was not working properly and there is a VTK version that works.
