   My solution for issue #46835 is almost ready. However, when 
`arrow::EqualOptions` is enabled, we should handle the case of comparing memory 
references to prevent incorrect NaN comparisons. This is already handled in 
`arrow::Table::Equals` under the assumption that comparing floating-point 
values should behave like comparing integers. The solution to that issue is 
included in this PR. Therefore, should we finish this PR first, or incorporate 
its solution into the PR related to #46835?
