enhance: use milvus-storage internal C++ Reader API for Loon FFI (#45897)
This PR refactors the Loon FFI reader implementation to use
milvus-storage's internal C++ Reader API directly instead of the
external FFI interface.

Key changes:
- Replace external FFI calls (get_record_batch_reader, reader_destroy)
with direct C++ Reader API calls
- Add GetLoonReader() helper function to create Reader instances using
milvus-storage::api::Reader::create()
- Use MakeInternalPropertiesFromStorageConfig() instead of
MakePropertiesFromStorageConfig() to get internal properties
- Update NewPackedFFIReaderWithManifest() to deserialize column groups
from JSON manifest content directly
- Simplify GetFFIReaderStream() to use Reader::get_record_batch_reader()
and arrow::ExportRecordBatchReader() for Arrow stream export
- Change CFFIPackedReader typedef from ReaderHandle to void* for
flexibility
- Update milvus-storage dependency version to ba7df7b

This change improves code maintainability by using the native C++ API
directly and eliminates the overhead of going through the external FFI
layer.
