LUCENE-10263: Implement Weight.count() on NormsFieldExistsQuery (#477)

If all documents in the segment have a value, then `Reader.getDocCount()` will
equal `maxDoc` and we can return `numDocs` as a shortcut.

> Similar to LUCENE-10085, we can quickly get a count of documents that have a text field present by reading docCount() from the field's Terms instance if there are no deleted documents.
