Add Partition object resizing method Partition*::resize() (#774818) 

Add a resize() method to both Partition and PartitionLUKS classes.  They
take a reference Partition object, and update the position, size and
file system usage of *this Partition to match.  This is ready for taking
a partition returned from Resize/Move dialog and applying the change.

Bug 774818 - Implement LUKS read-write actions NOT requiring a
             passphrase
