IMPALA-15127: Support HBO for UnionNode cardinality
This extends HBO to support tracking and using cardinality of
UnionNodes. Only FE changes are needed.
The HBO key string of a UnionNode consits of the number of const
operands and the key strings of its children. The children strings are
sorted so the operand order doesn't matter.
Testing
- Added FE tests for HBO key strings.
- Added e2e tests on all UNION types.
