Is your feature request related to a problem or challenge? Please describe what you are trying to do.

All Array implementations must implement the JsonEqual trait. However:

• UnionArray will always panic
• DictionaryArray is incorrect (JsonEqual for DictionaryArray Only Compares Keys #2294)
• It is unclear to me why we would special case JSON
• It complicates making JSON an optional feature

Describe the solution you'd like

Rather than maintaining parallel logic to interpret serde_json::Value as arrow arrays, I wonder if we can just remove the JsonEqual functionality and encourage conversion to arrow arrays. I'm unclear of a use-case that would require highly-performant comparison of arrow and JSON data

Describe alternatives you've considered
