If a `CMakeLists.txt` or `CMAKE_TOOLCHAIN_FILE` sets a variable named `C`, `CXX`, or `CUDA`, we were previously comparing each enabled language name to the value of that variable, rather than the name itself. Double-quote the string to take advantage of policy `CMP0054`, but also add "x" prefixes to support projects that do not set the policy. Fixes: #22125
