The cost of setting up and executing a separate sub-build to do the download, update and patch steps required for FetchContent population can be significant with some platforms and CMake generators. Avoid the sub-build altogether by invoking the step scripts directly. Previously, if no generator was set (e.g. population was being done in script mode), a generator needed to be available on the default PATH. Since we no longer use a sub-build, this restriction is also now gone. Fixes: #21703
