Remove deprecated python functions

Several deprecated python API that have been around for a few years are now gone. This include :

• paraview.simple.CreateScalarBar(), replaced by paraview.simple.GetScalarBar().
• paraview.simple.WriteAnimation(), replaced by paraview.simple.SaveAnimation().
• paraview.simple.WriteImage(), replaced by paraview.simple.SaveScreenshot().
• paraview.simple.ImportCinema(), no longer supported since 5.9.
• paraview.compatibility.GetVersion().GetVersion(), because of float comparison issue.

Other deprecated behaviors have been removed :

• paraview.compatibility.GetVersion() cannot be compared with float values anymore.
• In paraview.simple.CreateView(), removed support for positional argument detachedFromLayout.
• In paraview.simple.SaveScreenshot(), removed support for optional argument ImageQuality.
• In paraview.simple.SaveAnimation(), removed support for optional argument DisconnectAndSave and ImageQuality.
