IMPALA-12784: Fix bug in ScanNode.getFilteredInputCardinality
IMPALA-12018 adds method ScanNode.getFilteredInputCardinality(), which
is intended to return filteredInputCardinality_ if it set, but
mistakenly return filteredCardinality_ instead.
filteredInputCardinality_ is only affected by partition runtime filter
or runtime filter pushed to Kudu. On the other hand,
filteredCardinality_ is affected by all runtime filter consumed by a
ScanNode. This patch fixes the bug.
This patch also adds TRACE log at the end of
ScanNode.reduceCardinalityByRuntimeFilter()
Testing:
- Pass FE tests.

> Issue Type: Improvement
> Components: Frontend
> Reporter: Csaba Ringhofer
> Assignee: Riza Suminto
> Priority: Major
> Fix For: Impala 4.4.0
>
>
> Currently Impala creates a plan first and looks for runtime filters bases on
> the complete plan.
> IMPALA-3573 is about considering runtime filters during join ordering which
> would be a major change. Meanwhile it could be also useful to consider
> selective looking runtime filters in resource estimates without changing the
> plan topology.
