fix: Enhance streamer tests

Moved streamer open calls just before execute_command_lists.
Removed zeEventQueryStatus() check from streamer tests since they have a dedicated test.
Adjusted notifyNReport and samplingPeriod values to minimize the test runtimes.
Added a new read function in harness to read specific number of reports.
