[BugFix] fix tablet writer add chunk when larger than 2GB

[luohaha]

Why I'm doing:

There two issues now when handle >2GB chunk:

1. starrocks.PTabletWriterAddChunksRequest exceeded maximum protobuf size of 2GB: 4194416177

void serialize_to_iobuf(const T& proto_obj, butil::IOBuf* iobuf) {
    butil::IOBuf tmp_iobuf;
    butil::IOBufAsZeroCopyOutputStream wrapper(&tmp_iobuf);
    proto_obj.SerializeToZeroCopyStream(&wrapper);

SerializeToZeroCopyStream will fail when handle >2GB chunk.

2. In previous pr [BugFix] Fix brpc continuously fail after backend host restart #40229, It introduced a bug about missing set http protocol for BRPC client.

 input_messenger.cpp:96] A message from 172.26.94.64:39672(protocol=baidu_std) is bigger than 2147483648 bytes, the connection will be closed. Set max_body_size to allow bigger messages

What I'm doing:

Fix these two issues:

1. Seperate chunk from protobuf, so SerializeToZeroCopyStream won't fail because of >2GB serialize.
2. Set http protocol for brpc::ChannelOptions when handle >2GB RPC.
