Anatol Belski d9b188c1be block: qcow: Add pread_alloc and decompress_cluster helpers ...

Add two reusable helpers for the compressed cluster read path:

- pread_alloc(fd, offset, len) allocates a buffer and fills it with
  pread_exact, returning the owned Vec.
- decompress_cluster(compressed, cluster_size, decoder) allocates the
  output buffer, decodes via the Decoder trait, and validates that the
  decoder produced exactly cluster_size bytes.

These will be used by QcowSync, QcowAsync, Qcow2Backing, and the
legacy QcowFile.
