[Feature] Support lance file format

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar.

### Motivation

Lance format provides better support for machine learning. It can better support point lookup and wide columns to support vectorized data storage.

Do we have a plan to support this file format? Can you share your thoughts? Thanks. @JingsongLi @SteNicholas

Start by reading the linked Lance format documentation and the Lance v2 overview, then inspect Apache Paimon's existing file-format support to determine the integration scope. Done means reaching agreement on the design and implementing verified support for Lance as vectorized storage, with tests covering the supported behavior.
