[I] [C++][Parquet] parquet::arrow FileReader and FileReaderBuilder might multiple different memory pool [arrow]

mapleFU opened a new issue, #38320:
URL: https://github.com/apache/arrow/issues/38320

   ### Describe the enhancement requested
   
   ```C++
   class PARQUET_EXPORT FileReader {
    public:
     /// Factory function to create a FileReader from a ParquetFileReader and properties
     static ::arrow::Status Make(::arrow::MemoryPool* pool,
                                 std::unique_ptr<ParquetFileReader> reader,
                                 const ArrowReaderProperties& properties,
                                 std::unique_ptr<FileReader>* out);
   
     /// Factory function to create a FileReader from a ParquetFileReader
     static ::arrow::Status Make(::arrow::MemoryPool* pool,
                                 std::unique_ptr<ParquetFileReader> reader,
                                 std::unique_ptr<FileReader>* out);
   ```
   
   Here:
   1. `ParquetFileReader` uses it's memory using pool in `ReaderProperties`
   2. `FileReader` has a `MemoryPool` for building arrow.
   
   So this distinct the parquet arrow reader to possible two memory pool. Is this expected?
   
   ### Component(s)
   
   C++, Parquet
