feat(datafusion): Support pushdown more datafusion exprs to Iceberg

[FANNG1]

fixes: #644

DataFusion expressions and Iceberg predicates do not have a one-to-one correspondence.

1. Columns and literals are represented as Expr in DataFusion, whereas they are merely components of predicates in Iceberg.
2. And and Or are operators in DataFusion, but they are treated as predicates in Iceberg.

This disparity complicates the transformation process when using TreeNode. To address this, I also refactored the code to simplify it.
