update_engine: use cow_size_info
Updating update_engine to use a struct called CowSizeInfo which contains
extra parameters needed in v3 of cow format. These fields should be set
in delta archive manifest and passed to snapshot.cpp which will then
use the fields to correctly configure the cow with a correctly sized
operation buffer space.
