New ContentProviderOperation to assert values during batch.

When performing a set of batch operations, some callers need
to enforce that a query has specific values.  For example,
when persisting edited Contact values, we need to assert
that the RawContacts.VERSION matches the version we read out
through queryEntities().

This change adds a new TYPE_ASSERT that uses withValues()
and withSelection(), and checks all values when applying the
batch operation, bailing if any values don't match.
