[bug#57679] [RFC PATCH] gnu: Add paraview.

Attached is an earlier version of Paraview (5.9.1) that has been
submitted by Ontje (in Cc).

@Ludo: there doesn’t seem to be a way to unbundle VTK, because Paraview
is closely tied to VTK, reuses its build system to some extent, and is
better understood as an *extension* to VTK than a client application
using VTK merely as a library.  Upstream also commented that unbundling
VTK is not a priority and would have to be supported by the community.

About the icons: when I run /gnu/store/7x3dxk0kl0rc1sw673z51cfran7q6hf1-paraview-5.9.1/bin/paraview I
don’t see most icons.  Even when I install it into a profile that has
adwaita-icon-theme and run it from the profile in a new shell session
the icons are not displayed.

According to strace the icons are found (after searching in all the
wrong places — probably an opportunity for performance improvement), but
they are not displayed.

This is the same problem as https://issues.guix.gnu.org/29905.  The
problem disappears when QT_PLUGIN_PATH is set.  I tested this by
installing qtsvg@5 in my profile alongside paraview-5.9.  The icons
show up.

So I suggest wrapping the executables in QT_PLUGIN_PATH just as we did
for krita and itk-snap.
