Akilesh Kailash 4bc81b409b libsnapshot: Batch write COW operations in a cluster
COW operations are written in cluster. All the COW ops
and the COW data in this cluster are contiguous. Hence,
batch these writes and write them in one syscall.

Writes are done when the cluster is full or when
label ops are written.

OTA install time (without post-install) on Pixel 6 Pro:

          Without-this-patch        With-this-patch

Full OTA: 17 Minutes               13 Minutes

Following are the OTA install times with both the optimization.
viz - batch writes + 2 threads for compression.

OTA install (without post-install) on Pixel 6 Pro.

All numbers are in minutes.

Full ota - 2.2G
