X Title: GH-939: Remove reflection for gRPC buffers by xborder · Pull Request #954 · apache/arrow-java

Description: What's Changed Replace reflection-based gRPC buffer handling with FlightDataParser reading from InputStream/detached ByteBuffer, enabling zero‑copy ArrowBuf slices for app_metadata and data_body. Simplify ArrowMessage.frame to use the shared parser and fallback path; remove GetReadableBuffer and add grpc-core runtime/module updates. Add TestArrowMessageParse coverage for duplicate fields, zero‑copy allocation, and non‑detach fallback behavior. Closes #939.
