Ben Boeckel 306a1ba960 Modules/Documentation: remove
This is an old module from when VTK and other Kitware projects drove the
addition of commands and modules into CMake itself. Modern VTK doesn't
need this module and it can be ignored.

This module is kept around so that the ancient VTK versions which use it
are not broken by it. VTK itself stopped using the module in 2012 and
the last usage by an example in VTK was removed in 2020.

Fixes: #20591

CMP0106
-------
The :module:`Documentation` module is removed.
The :module:`Documentation` was added as a support mechanism for the VTK
project and was tuned for that project. Instead of CMake providing this module
with (now old) VTK patterns for cache variables and required packages, the
module is now deprecated by CMake itself.
The ``OLD`` behavior of this policy is for :module:`Documentation` to add
cache variables and find VTK documentation dependent packages. The ``NEW``
behavior is to act as an empty module.
This policy was introduced in CMake version 3.18. CMake version |release|
warns when the policy is not set and uses ``OLD`` behavior. Use the
:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
