IMPALA-8064: Improve observability of wait times for runtime filters

This change is a diagnostic fix to improve the wait times logged
for runtime filters. The filter wait time counts against the
elapsed time since the filter's registration in ScanNode::Init()
while the duration logged in ScanNode::WaitForRuntimeFilters() is
the time spent in the function waiting for all the filters to
arrive. This could be misleading as it doesn't account for the
elapsed time spent between ScanNode::Init() and
ScanNode::WaitForRuntimeFilters(). This change logs the maximum
arrival delay for any runtime filter to arrive.

>From my analysis of the logs of the failed tests, I believe the
filters are actually waiting for the specified time but logging
the duration incorrectly. The solution would be to increase the
wait time further. This change would help validate this
hypothesis.
