Add a new developer options screen for shared data.

Add a new Storage section in the developer options menu which has a
new Shared Data preference. This preference screen shows all shared data
blobs on the device. There is also a new screen for each data blob which
shows all of the packages which currently have a leases on it. This
screen also has a button to delete the shared data blob.
