Pull request overview
This PR cherry-picks the fix to allow MATCH predicates on aliased VARIANT subcolumn accesses in the Nereids rewrite validation path.
Changes:
- Updates
CheckMatchExpressionto unwrapCastandAliaschains before validating the left operand as aSlotReference. - Adds unit coverage for accepted alias/cast chains and rejected non-slot alias expressions.
- Adds an end-to-end VARIANT pruning test for
cast(msg.trace_id as string) match_phrase_prefix.

### What problem does this PR solve? Issue Number: None Related PR: apache#63772 Problem Summary: MATCH predicates fail for VARIANT dot subcolumn access such as cast(msg.trace_id as string), while the equivalent bracket access msg['trace_id'] works. Dot access can leave an Alias around the pruned subcolumn slot, and CheckMatchExpression rejected the aliased slot. ### Release note Fix MATCH predicates on VARIANT dot subcolumn access such as msg.trace_id so they are accepted like equivalent bracket subcolumn access. ### Check List (For Author) - Test: - Unit Test: ./run-fe-ut.sh --run org.apache.doris.nereids.rules.rewrite.CheckMatchExpressionTest - Unit Test: ./run-fe-ut.sh --run org.apache.doris.nereids.rules.rewrite.VariantPruningLogicTest#testMatchOnDotVariantSubColumnUsesSlotRefInScanPredicate - Behavior changed: Yes. MATCH validation now accepts alias/cast chains that resolve to a SlotReference, while still rejecting aliases over non-slot expressions. - Does this need documentation: No (cherry picked from commit d0cfb94) (cherry picked from commit 26abcfcdb9a04a3d7244ccad5d17c7bdd7a1dfa9)
