Disallow add_custom_command SOURCE signatures.
CMake 2.8.12 and lower allowed a signature for :command:`add_custom_command`
which specified an input to a command. This was undocumented behavior.
Modern use of CMake associates custom commands with their output, rather
than their input.
The ``OLD`` behavior for this policy is to allow the use of
:command:`add_custom_command` SOURCE signatures. The ``NEW`` behavior for this
policy is to issue an error if such a signature is used.
