This is essentially a revert of 9853e9b which tried removing duplication in the Windows config files by moving it to the CMake. However, we want to decouple the CMake and the test suite as much as possible, so encoding additional (non-official) Lit parameters in the CMake only as a code reuse mechanism is not an approach we want to take.
