FindITK: Drop this ancient compatibility module 

The FindITK module only existed to help find_package(ITK) calls work in
old projects written to use "USE_ITK_FILE" instead of "ITK_USE_FILE".
Drop it to allow find_package(ITK) calls to search for ITKConfig.cmake
directly.

FindITK
-------
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(ITK NO_MODULE)`` to
provide compatibility for projects using long-outdated conventions.
Now ``find_package(ITK)`` will search for ``ITKConfig.cmake``
directly.

#.rst:
# FindITK
# -------
#
# Find an ITK installation or build tree.
# When ITK is found, the ITKConfig.cmake file is sourced to setup the
# location and configuration of ITK. Please read this file, or
# ITKConfig.cmake.in from the ITK source tree for the full list of
# definitions. Of particular interest is ITK_USE_FILE, a CMake source file
# that can be included to set the include directories, library directories,
# and preprocessor macros. In addition to the variables read from
# ITKConfig.cmake, this find module also defines
# ITK_DIR - The directory containing ITKConfig.cmake.
# This is either the root of the build tree,
# or the lib/InsightToolkit directory.
# This is the only cache entry.
#
# ITK_FOUND - Whether ITK was found. If this is true,
# ITK_DIR is okay.
#
# USE_ITK_FILE - The full path to the UseITK.cmake file.
# This is provided for backward
# compatibility. Use ITK_USE_FILE
# instead.
