Windows: Revert "Prefer junctions for directory symlinks"

Revert commit 5101d586c4 (Windows: Prefer junctions for directory
symlinks, 2022-02-22, v3.24.0-rc1~575^2).  Junctions do not support
`../` and other non-canonical paths.  Revert their use pending further
investigation.

Fixes: #23781
Issue: #23257
