Description
### Describe the enhancement requested
Currently, `ArrayFromJSONString` doesn't support emitting run-end-encoded data.
Like dictionary-encoded data, this could be implemented in two ways:
1. Implement implicit run-end encoding in `ArrayFromJSONString` when a REE type is given
2. Expose a separate function to explicitly pass the run ends and values, for example `REEArrayFromJSONString(const std::shared_ptr&, std::string_view run_ends_json, std::string_view values_json)`
