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 apacheGH-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; page level statistics additionally require the page index to be enabled.
