LUCENE-10272: cross-check norms with postings in checkindex (#493)
Previously, CheckIndex would iterate norms and validate each one. But if norms
that should be there were missing, nothing would fail. Now it computes an
expected count of norms and ensures it saw them all.

> Spinoff from LUCENE-10271
> Despite the current crazy ghost values / elasticsearch abuse of norms, we
> should still cross-check the data in checkindex.
> Terms.getDocCount should equal the number of norms (we just ignore the bogus
> ghost values for now).
> Currently checkindex is missing really any check of norms: and it turns out
> that non-aborting exceptions create inconsistencies.
