Adds a def file to have a single location where tested language versions are specified. Removes the need to update multiple locations in the testing infrastructure to add a new language version to be tested. Test instatiation can now include all languages without needing to specify them. This patch also adds pretty printing for instantiated test names. That means, that a test instantiated with C++23 will have the name `...TestSuite/TestName/CXX23` instead ending with some number (index of the argument for instantiation of the test), which provides a better experience when encountering a test failure with a specific language version. The suffix will also contain an `_win` if the target contains `win`. --------- Co-authored-by: Sirraide <aeternalmail@gmail.com>
