Change subject: IMPALA-11443: Fix partitoned top-n with -1 input cardinality

IMPALA-11443: Fix partitoned top-n with -1 input cardinality
Creating a plan with partitioned top-n node with -1 input
cardinality led to having negative resource estimate and
hitting a precondtition, returning error:
"IllegalStateException: Mem estimate must be set"
This change adds handling for unknown cardinality.
Testing:
- added a planner test
