SnapshotMergeReported: add retrofit and cow image size
Additional information are important to evaluate the impact of Virtual
A/B on devices especially related to OTA take rate.
Take rate is strictly related to the space that is temporarily allocated
in the /data partition (cow_file_size_bytes), as well as knowing if the
device has been upgraded to use Virtual A/B (is_vab_retrofit) or if the
feature was natively supported.
Add these new fields to the SnapshotMergeReported metric.
