The sub-build should never try to use a toolchain file. The toolchain file may itself be getting downloaded by FetchContent. If the CMAKE_TOOLCHAIN_FILE environment variable is set, CMake uses it to initialize the CMake variable of the same name. We need to explicitly clear them before the first project call of the sub-build. Fixes: #24535
