fix(@angular-devkit/build-angular): ENOENT: no such file or directory on Windows during component rebuild

Previously, we `joined` the workspace root with the `outputFile.path`, in windows this caused a problem as during the 2nd rebuild it caused the workspace root to be prepended again which causes a `ENOENT` error. To avoid this problem, now we `clone` the output file.

Closes #26900
