Add `RewriteFiles` support to iceberg-rust

### Is your feature request related to a problem or challenge?

Currently, `iceberg-rust` does not support committing operations that both add and delete files. This feature, known as `RewriteFiles` in `iceberg-java`, is crucial for our use case, particularly for compaction.

### Describe the solution you'd like

Based on my initial investigation in #1606, I believe the following three components are necessary to implement `RewriteFiles` in `iceberg-rust`:

- **Process delete files**: We need to add logic to handle delete files when generating snapshots.
- **Implement `RewriteFilesAction`**: This will require creating a new transaction action, `RewriteFilesAction`, and related classes like `RewriteFilesOperation`.
- **Support validation**: We need to add validation for rewrite operations to prevent conflicts. Currently we don't have any validation mechnism in the codebase, so a new trait `SnapshotValidator` would be needed.

### Willingness to contribute

I would be willing to contribute to this feature with guidance from the Iceberg Rust community
