Module datafusion_optimizer::unwrap_cast_in_comparison

Unwrap-cast binary comparison rule can be used to the binary/inlist comparison expr now, and other type of expr can be added if needed. This rule can reduce adding the Expr::Cast the expr instead of adding the Expr::Cast to literal expr.

• UnwrapCastInComparison
  UnwrapCastInComparison attempts to remove casts from comparisons to literals (ScalarValues) by applying the casts to the literals if possible. It is inspired by the optimizer rule UnwrapCastInBinaryComparison of Spark.
