thanks for reducing the refactor PR size :)

FYI @cugni : I've opened a new issue with a more fine-grained scope than the Delta Refactor, and I've also changed the PR title with the Issue number linked. |

Description
This PR is working toward the abstraction of Qbeast-spark from Delta code #398. It makes the RollupDataWrite more independent of the Open Table Format used and reorganizes the roles of accessing the data between the DataWriter and the QbeastSnapshot. This PR also solves a potential issue when optimizing a table with a changed schema.
