`CMAKE_<LANG>_COMPILER` may be a list if it was defined by a toolchain file. In this case we move the args to `CMAKE_<LANG>_COMPILER_ARG1`. If `CMAKE_<LANG>_COMPILER` is not a list, then it might have been cached by a previous run that split the `CC` or `CXX` environment variable into `CMAKE_<LANG>_COMPILER` and `CMAKE_<LANG>_COMPILER_ARG1`. In this latter case, avoid clobbering `CMAKE_<LANG>_COMPILER_ARG1`. Fixes: #23358
