CONFIG: update versions for paraview (#3537)

- drop old TCL support from paraview build.

- add +plugins variant to have include directories installed. This is
  enabled by default since the additional diskspace for includes is
  really minimal and since this also allows re-use of the VTK libraries
  from ParaView without necessarily requiring a separate VTK
  installation.

- +opengl2 is now the default. As per all newer VTK and paraview versions.

BUG: broken install for paraview-5.0.1 with includes and without python

- incorrect conditional for ui_pqExportStateWizard.h when python is
  disabled and includes are to be installed.
  gcc compiler detection patch.
  These have both been fixed in paraview 5.3.0

ENH: refactor as a CMakePackage.

- Note that "spack install paraview" works as expected, but
  "spack build paraview" fails in weird unrelated ways.
