Pass extra when evaluating lockfile markers (#9539)

## Summary

When we serialize and deserialize the lockfile, we remove the conflict
markers. So in the linked case, the edges for the `tqdm` entries are
like:

```
complexified_marker: UniversalMarker {
    pep508_marker: python_full_version >= '3.9.0',
    conflict_marker: true,
},
```

However... when we evaluate in-memory, the conflict markers are still
there...

```
complexified_marker: UniversalMarker {
    pep508_marker: true,
    conflict_marker: extra == 't1' and extra != 't2',
},
```

So if `uv run` creates the lockfile, we evaluate this as `false`.

We should make this consistent, and I expect @BurntSushi is aware. But
for now, it's reasonable / correct to pass the extra when evaluating at
this specific point, since we know the dependency was enabled by the
marker.
