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

In #5481 we added support for StringViewArray and ByteViewArray.

This ticket tracks supporting StringViewArray and ByteViewArray in the filter kernel: https://docs.rs/arrow/latest/arrow/compute/kernels/filter/index.html

Describe the solution you'd like

  1. Support StringViewArray and ByteViewArray the filter kernel
  2. Add tests

Notes:

  1. you should be able to follow the model of DictionaryArray as the idea is similar
  2. Filtering should not copy any strings, it should just manipulate the fixed size views

Describe alternatives you've considered
