Instead of using junctions, we can just write files that contain (as the file contents) the target path. This requires a little more finesse in that, as readers, we need to know where to expect these. But it also means we get to avoid junctions, which have led to a variety of confusing behaviors. Further, `replace_symlink` should now be on atomic on Windows. Closes #11263.
