Modernize `<DartMeasurement>` tags to `<CTestMeasurement>`

[dennisklein]

Starting from CMake 3.22 it is supported to use <CTestMeasurement> instead of <DartMeasurement>, see gitlab.kitware.com/cmake/cmake/-/commit/373608831099bf96f568d9db5cb12a3f9092edf4.

Let's adopt this once we bump minimum required CMake version to 3.22+.
