Verify the extents for untouched dynamic partitions during partial update
For partial updates, the metadata for untouched dynamic partitions are just copied over to the target slot. So, verifying the extents of these partitions in the target metadata should be sufficient for correctness. This saves the work to read & hash the bytes on these partitions for each resumed update. Bug: 151088567 Test: unit tests pass, apply a partial update Change-Id: I9d40ed2643e145a1546ea17b146fcdcfb91f213f
