[I] Support column and partition stats with Lance file format [hudi]
yihua opened a new issue, #18758:
URL: https://github.com/apache/hudi/issues/18758
### Task Description
Currently, column stats and partition stats are not supported with Lance file format. Such support needs to be added.
Particularly, `LanceUtils` does not implement reading column stats metadata from the Lance files.
```
@Override
public List<HoodieColumnRangeMetadata<Comparable>> readColumnStatsFromMetadata(HoodieStorage storage,
StoragePath filePath,
List<String> columnList,
HoodieIndexVersion indexVersion) {
throw new UnsupportedOperationException("readColumnStatsFromMetadata is not yet supported for Lance format");
}
```

Hello maintainers, I would like to work on this task. I will inspect LanceUtils metadata handling, implement column and partition statistics extraction for Lance files, and add tests covering HoodieColumnRangeMetadata generation. Please assign this to me.
