Anatol Belski 73d99c044c performance-metrics: Add sparse QCOW2 tempfile helper ...

Add sparse_qcow_tempfile() which creates a QCOW2 image with one
allocated cluster per L2 table, spread across num_l2_tables distinct
L2 tables.  Reading these clusters in sequence forces L2 cache misses
when the count exceeds the cache capacity.

Also add the L2_ENTRIES_PER_TABLE constant, 8192 for 64 KiB clusters.

To be used by the L2 cache cold miss benchmark.
