Deprecate compatibility with CMake versions older than 3.5

Issue a deprecation warning on calls to `cmake_minimum_required` or
`cmake_policy` that set policies based on versions older than 3.5.
Note that the effective policy version includes `...<max>` treatment.
Update the check from commit 5845c218d7 (Deprecate compatibility with
CMake versions older than 2.8.12, 2020-06-12, v3.19.0-rc1~629^2).

   Policy CMP0058 is not set: Ninja requires custom command byproducts to be
   explicit.  Run "cmake --help-policy CMP0058" for policy details.  Use the
   cmake_policy command to set the policy and suppress this warning.
