Improve ArraySegmentStream with ReadOnlyMemory/Span signatures, avoid…

… extra alloc/copy (#2556)

- Implement `int Read(Span<byte> buffer)` and `void Write(ReadOnlySpan<byte> buffer)` in ArraySegmentStream
- for ArraySegmentStream streaming lower the CPU load for .NET8 OPC UA binary encoding/decoding by 50%
- Implement dispose to return buffers that were not transferred. 
- Implement a GetSequence in ArraySegmentStream
