Anatol Belski 13198777dd block: qcow: Add support for zero bit in standard L2 clusters ...

Implement read support for bit 0 in QCOW2 L2 table entries.
When this flag is set, the cluster reads as zeros without accessing
disk. This improves compatibility with QCOW2 images that use this
optimization.

According to the QCOW2 specification, bit 0 of the standard cluster
descriptor indicates that the cluster reads as zeros. Unlike
l2_entry == 0 indicating a completely unallocated entry, bit 0 can
be set on an allocated cluster.
