d2ad53cf81 Add CowOperationV2 
this is going to replace the current version of CowOperation and will
work with writer v2 and parser v2. This will be the on disk format of
the cow, while CowOperation will be updated to be the in memory format
of 15 bytes (implicitly will be the v3 version).

bcae6b5e60 libsnapshot_cow: Prepare device to boot from pre-created snapshots 
Two new API's have been added:

1: BootFromSnapshotsWithoutSlotSwitch: This will create a new marker
which indicates first-stage init to mount the partitions off snapshots.

We need this marker as during boot, there are couple of places during
mounting snapshots wherein the marker is used. However, there is no
change in the existing I/O path related to OTA.

2: PrepareDeviceToBootWithoutSnapshot: This will delete the marker so
that subsequent reboot will not have the partitions mounted without the
snapshots.

VTS tests covers both these API's. Additionally, when these
markers are present, new OTA's cannot be installed. All these
are covered in VTS tests.

===========================================================

snapshotctl: General flow to apply and revert pre-created snapshots

1: To install the pre-created snapshots:

$snapshotctl map-snapshots <directory path containing snapshots patches>

Now the device is ready to boot from snapshots.

2: After device reboots, partitions are mounted off the snapshots. There
   is no snapshot-merge.

3: In order to go back to previous build:

$snapshotctl revert-snapshots

Now the device is ready to boot from base build.

4: After device reboots back to previous build, all the snapshot states
   and COW images are removed.

============================================

Additional commands:

To delete the pre-created snapshots:

$snapshotctl delete-snapshots

======================================

Tested it on Pixel 6 Pro between two builds which are ~24 hours apart.

1: Creating snapshots on a linux-host - ~4-6 seconds
2: Applying pre-created snapshots - ~10-15 seconds (includes intermediate
   transfer of patches to the device). This depends on the size of snapshot patches.
3: Device reboot - ~12-14 seconds.

Bug: 299011882
Test: 1: Apply pre-created snapshots
2: Reboot device: Verify new build
3: Apply OTA when partitions are mounted of snapshots and verify OTA
   fails.
3: Revert-snapshot and reboot.
4: Verify device goes back to base build.

Full OTA on Pixel. vts_libsnapshot_test
