[I] Enhance InExpr in gandiva which can use more easily [arrow]
likun666661 opened a new issue, #39492:
URL: https://github.com/apache/arrow/issues/39492
### Describe the enhancement requested
In the current Gandiva in expression, it can take an expression as input, along with a constant set for filtering conditions. The current in expression in Gandiva supports forms like in(add(x+b), {3, 4}). However, if a user wants to use a form like in(add(x+b), {length(str), c+1, 7+9}), it is not supported. The user must manually expand it into expressions like add(x+b) == length(str) or add(x+b) == add(c+1) or add(x+b) == 7+9. We aim to introduce a Gandiva in expression syntactic sugar that allows users to avoid manually expanding the in expression into an or expression. Additionally, we hope to optimize performance for cases with common subexpressions.
### Component(s)
