IMPALA-14958: Fix missing lifecycle events for some nodes

Node Lifecycle Events in profile are incomplete for KuduScanNodeMt,
IcebergMetadataScanNode and SystemTableScanNode. It's fixed by adding
the invocation of ScopedOpenEventAdder and ScopedGetNextEventAdder in
the corresponding Open and GetNext implementations.

Also adds/adjusts the total time counter in some nodes.

Testing
 - Added e2e tests
 - Improved the timeline checking by verifying all the occurrences.
