FindVTK: Drop this ancient compatibility module

The FindVTK module only existed to help find_package(VTK) calls work in
old projects written to use "USE_VTK_FILE" instead of "VTK_USE_FILE".
Drop it to allow find_package(VTK) calls to search for VTKConfig.cmake
directly.

+FindVTK
+-------
+
+This module no longer exists.
+
+This module existed in versions of CMake prior to 3.1, but became
+only a thin wrapper around ``find_package(VTK NO_MODULE)`` to
+provide compatibility for projects using long-outdated conventions.
+Now ``find_package(VTK)`` will search for ``VTKConfig.cmake``
+directly.

-# FindVTK
-# -------
-#
-# Find a VTK installation or build tree.
-#
-# The following variables are set if VTK is found.  If VTK is not found,
-# VTK_FOUND is set to false.
-#
-# ::
-#
-#   VTK_FOUND         - Set to true when VTK is found.
-#
-# The following cache entries must be set by the user to locate VTK:
-#
-# ::
-#
-#   VTK_DIR  - The directory containing VTKConfig.cmake.
-#              This is either the root of the build tree,
-#              or the lib/vtk directory.  This is the
-#              only cache entry.
-#
-# The following variables are set for backward compatibility and should
-# not be used in new code:
-#
-# ::
-#
-#   USE_VTK_FILE - The full path to the UseVTK.cmake file.
-#                  This is provided for backward
-#                  compatibility.  Use VTK_USE_FILE
-#                  instead.
