Add support for VTK9

VTK 9 changes the CMake interface pretty significantly. To get ACVD working with VTK 7, 8, and 9, we need to address at least the following:

• No more VTK_USE_FILE (handled in !9 (merged))
• VTK library targets now have CMake prefixes (e.g. vtkCommonCore -> VTK::CommonCore)
• Missing includes, symbols, and definitions when the above are fixed. This implies missing includes or linkage somewhere.
