Core: Stream DV Puffin rewrite in RewriteTablePathUtil to reduce memory pressure

### Feature Request / Improvement

### Description

`RewriteTablePathUtil.rewriteDVFile` currently rewrites deletion vector (DV) Puffin files by reading all rewritten blobs into an in-memory list before writing them out, which can create unnecessary memory pressure when rewriting larger DV files or files with many blobs.

### Suggested improvement

Refactor `RewriteTablePathUtil.rewriteDVFile` to stream rewritten blobs directly to the output `PuffinWriter` while iterating through the source blobs, instead of collecting all rewritten blobs into a temporary list first.
