os: don't normalize volumes to drive letters in os.Readlink
This CL updates os.Readlink so it no longer tries to normalize volumes
to drive letters, which was not always even possible.
This behavior is controlled by the `winreadlinkvolume` setting.
For Go 1.23, it defaults to `winreadlinkvolume=1`.
Previous versions default to `winreadlinkvolume=0`.
Fixes #63703.
