Ah no, I'm probably breaking something on Windows. I got lazy and assumed that Windows failures were timeouts after the macOS runner passed. Incorrect! |

Ok, "canonicalize -> simple_canonicalize" fixed it. |
Previously we were using the XDG data dir to avoid symlinks, but there's no particular guarantee that that's not going to be a symlink too. Using the canonicalized temp dir by default is also slightly nicer for a couple reasons: It's sometimes faster (an in-memory tempfs on e.g. Arch), and it makes overriding `$TMPDIR` or `%TMP%` sufficient to control where tests put temp files, without needing to override `UV_INTERNAL__TEST_DIR` too.

## Summary This came up on [Discord](https://discord.com/channels/1039017663004942429/1343692072921731082/1395447082520678440) and also in #19387, but on macOS the tmp directory is a symlink to `/private/tmp`, which breaks this filter. I'm still not quite sure why only these tests are affected when we use the `tempdir_filter` elsewhere, but hopefully this fixes the immediate issue. Just `tempdir.path().canonicalize()` also worked, but I used `dunce` since that's what I saw in other tests (I guess it's not _just_ these tests).

Now to make sure it passes on Windows, which caused most of the trouble in the first PR!
