Remove some unnecessary use of Path.resolve(). NFC (#25488)

It looks like this was first introduced in #17102 as a replacement for
`os.path.normpath`, but its not actually same thing `os.path.normpath`
does not resolve symlinks.

Apparently resolving symlinks can actually cause crashes on windows in
some cases. See #25463.

Fixes: #25463
