URL: https://github.com/apache/doris/pull/64440
### What problem does this PR solve?
visitMapContainsKey/Value/Entry only visited the map argument
(getArgument(0)) and skipped the key/value/entry argument (getArgument(1)).
When the key is a nested sub-column expression (e.g. element_at(s, 'a')) and
the same sub-column also appears in IS NULL, NestedColumnPruning would only see
[s.a.NULL] and prune the column to null-only metadata access.
Fix: after visiting the map argument, also visit the second argument with a
fresh context to register its data access paths.
Regression test map_contains_arg_pruning covers:
- map_contains_key with struct sub-column key + IS NULL
- map_contains_value with struct sub-column value + IS NULL
- Combined key + value sub-column access
