Arrow Flight format support for StringViewArray and BinaryViewArray

[alamb]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
This is part of the larger project to implement StringViewArray -- see #5374

This ticket tracks adding Arrow Flight support

Describe the solution you'd like
Since Arrow Flight is based on the IPC format, #5506 may be sufficient.

To close this ticket, we should add tests that demonstrate sending / receiving StringViewArray and BinaryViewArray over Arrow flight (e.g. using FlightDataEncoder)

Describe alternatives you've considered

I can take a look at this (as a way to teach myself some arrow flight knowledge). I have limited bandwidth though, so feel free to bypass me and pushing this forward.

Thanks @XiangpengHao -- I think the first thing to do is write a test for StringViewArray and BinaryViewArray for the data encoder/decoder: https://github.com/apache/arrow-rs/blob/master/arrow-flight/tests/encode_decode.rs (I think you can just follow the existing examples)

It may be the case that it "just works" 🙏
