This adds a global fixture that can parse an additional argument to the test executables (`--generate_ctest_config`). When run by CMake during build, this generates a CTest script containing all the tests and their properties. An additional decorator, that defines CTest properties for a test case or suite that will be added to the tests during config generation. This version needs no hacks, no huge CMake scripts, just a bit of additional C++ code that iterates over all test-cases and collects the information CTest needs. One caveat is still that this does not work with cross-compilation, which probably isn't an issue to begin with, but there are also ways to fix that if necessary.
