Integrate the StorageV2 FFI interface as the unified storage layer for
reading packed columnar data, replacing the custom iterative reader with
a manifest-based approach using the milvus-storage library.
Changes:
- Add C++ FFI reader implementation (ffi_reader_c.cpp/h) with Arrow C
Stream interface
- Implement utility functions to convert CStorageConfig to
milvus-storage Properties
- Create ManifestReader in Go that generates manifests from binlogs
- Add FFI packed reader CGO bindings (packed_reader_ffi.go)
- Refactor NewBinlogRecordReader to use ManifestReader for V2 storage
- Support both manifest file paths and direct manifest content
- Enable configurable buffer sizes and column projection
Technical improvements:
- Zero-copy data exchange using Arrow C Data Interface
- Optimized I/O operations through milvus-storage library
- Simplified code path with manifest-based reading
- Better performance with batched streaming reads

This parameter determines whether the returned value should be a copy or
a reference from the arrow array. The updates enhance memory management
and provide more control over data handling during deserialization.
