performance-metrics: Add QCOW2 async random read micro benchmark

Browse Source 
Add micro_bench_qcow_async_random_read which reads clusters in
random order through the QcowAsync io_uring path. This mirrors
the existing sync random read benchmark and measures io_uring
completion handling under random access patterns.
