[BugFix] If the operator is AND, return the predicates that are not null for paimon (backport #66038)

[mergify]

Why I'm doing:

For the following predicate:
f0 = 44 and (case when f0 = 44 then f1 else f2) = 33,
Paimon cannot parse the predicate (case when f0 = 44 then f1 else f2) = 33, and the predicate conversion returns null.
Normally, the predicate f0 = 44 should be retained.

What I'm doing:

Fixes #issue

Note

Improves Paimon predicate conversion robustness and partial-predicate preservation.

• Add PaimonPredicateContext to track parent CompoundPredicateOperator
• Update PaimonPredicateConverter to accept PaimonPredicateContext and propagate it to children
• For AND, return the non-null predicate when one side is unconvertible; under parent NOT, return null to avoid invalid partials; keep NOT over LIKE unsupported
• Update visitor method signatures to use the new context
• Add testOrWithFunction validating mixed OR/AND/NOT with CASE WHEN and LIKE
