[PR] [Python][Parquet] Expose size statistics level in the Parquet writer [arrow]

["abaybek (via GitHub)" <gi...@apache.org>]

abaybek opened a new pull request, #50621:
URL: https://github.com/apache/arrow/pull/50621

   ### Rationale for this change
   Add a `write_size_statistics` keyword to `pyarrow.parquet.write_table`, `ParquetWriter`, and the dataset write path. It exposes the C++ `parquet::WriterProperties::Builder::set_size_statistics_level` setter introduced in GH-40592, accepting "none", "columnchunk", or "pageandcolumnchunk" (None keeps the Arrow C++ default of "pageandcolumnchunk").
   
   Size statistics are written by default, and until now there was no way to disable or tune them from PyArrow. "none" turns them off entirely..
   
   ### What changes are included in this PR?
   Python/Cython client only — no C++ changes (the underlying setter already exists since Arrow 19.0.0).
   
   ### Are these changes tested?
   Yes, added a test cases to python/pyarrow/tests/parquet/test_basic.py. Also tested against legacy readers.
   
   ### Are there any user-facing changes?
   Yes, a new optional write_size_statistics keyword.
