Test for creating and reloading usage entries.

Browse Source 
[ Merge from http://go/wvgerrit/102303 ]

This adds an OEMCrypto test that ensures that usage entries can be
loaded and reloaded without issue within the same crypto client
lifecycle.  This is in response to b/158273241 where certain entries
could not be reloaded if new entries are created and loaded in a
particular order.
