[C#] ArrowStreamReader does not handle empty stream well

[keshen-msft]

Describe the bug, including details regarding any error messages, version, and platform.

When input stream is empty, the reader throws exception when reading the schema, refer to

arrow/csharp/src/Apache.Arrow/Ipc/ArrowStreamReaderImplementation.cs

Line 157 in cd607d0

int schemaMessageLength = await ReadMessageLengthAsync(throwOnFullRead: true, cancellationToken)

. Exception details:

System.InvalidOperationException
HResult=0x80131509
Message=Unexpectedly reached the end of the stream before a full buffer was read.

On the other hand, javascript handles such input. And C++ lib also handles it, refer to https://github.com/apache/arrow/blob/cd607d00b9e3c5f2ac2a2e373ba7571fd75fc725/cpp/src/arrow/ipc/reader.cc#L1109C7-L1111C10. The behavior in javascript and C++ is that null RecordBatch is returned.
