[CH]Remove ParquetException

### Description

```cpp
int64_t col_length = column_metadata.total_compressed_size();
int64_t col_end;
if (col_start < 0 || col_length < 0)
throw parquet::ParquetException("Invalid column metadata (corrupt file?)");
```

The issue provides only a C++ snippet, so first locate the column-metadata validation containing ParquetException and read its surrounding call path. Check the project’s relevant native tests or build after the change; done means the requested exception removal is covered without leaving the invalid-metadata case unhandled.
