Add option to create clang-tidy ninja script file

Description:

Add an option to create a ninja script that runs clang-tidy on the source files.

If you are using CMake directly on a CMakeLists.txt file using the MSVC compiler, then getting clang-tidy to work is problematic at best. Since it dramatically slows down compilation, it would be useful if instead there was a specific ninja script that ran it. This could then be run manually or even as part of a CI build if the ninja script file was added to SCM.
