Frameworks/base: Remove UsageEvents finalizer

The order of finalization between the parcel and the UsageEvents
objects is not defined. In the bad case, the parcel will be
finalized first and destroy its native pointer, after which the
UsageEvents object will recycle it, putting it back into one of
the Parcel pools. This will violate the pool invariant.
