Mark Olesen 628b2445fc ENH: improve setup for paraview
- removed reliance on ParaView_INCLUDE_DIR variable for conveying the
  major.minor version information when compiling. This can be somewhat
  fragile and also adds variable that is an unnecessary when running
  (only used when compiling).

  Instead use `have_pvplugin_support` function in paraviewFunctions
  wmake script to determine the maj.min from the PV_PLUGIN_PATH
  since we have already defined the output path there with paraview
  maj.min numbering.

  Can now build with paraview from the operating system,
  provided that it has develop headers available.

      ParaView_VERSION=system

  In the etc/config.sh/paraview setup, the maj.min is taken from
  the corresponding `paraview --version` output and used when
  defining the PV_PLUGIN_PATH.

  During the build, the include path taken from `paraview-config`
  for a system installation, from the guess installation root
  of the paraview binary, or ParaView_DIR otherwise.

NB: using a system ParaView for building runTimePostProcessing is unsupported.

- these types of builds appear to have various library resolution issues
  (eg, libexpat not being loaded). Additionally, the build logic does
  not yet cover this type of use case.
