Add multi-variant overloads for PDOStatement::fetchAll() in function signature map

- Replace the single `PDOStatement::fetchAll` signature (which combined all
  parameter types into one union) with proper multi-variant overloads matching
  `PDO::query` and `PDOStatement::setFetchMode` patterns
- Add variant '1 for FETCH_COLUMN mode (int $mode, int $colno)
- Add variant '2 for FETCH_CLASS mode (int $mode, string $classname, ?array $ctorargs)
- Add variant '3 for FETCH_FUNC mode (int $mode, callable $callback)
- Update both base functionMap.php and functionMap_php80delta.php
- Verified PDO::query and PDOStatement::setFetchMode already had correct overloads
