Help: Document explicitly that policy OLD behavior is deprecated
The most likely documentation page a project author will read in response to a policy warning is the page for the policy itself. Add to every policy documentation page a note explicitly stating that the OLD behavior is deprecated. Also mention this in the cmake_policy() command documentation that explains how to set a policy to OLD. Suggested-by: Fraser Hutchison <fraser.hutchison@gmail.com>
