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
