LUCENE-9999: CombinedFieldQuery can fail with an exception when document is
missing fields (#185)
This change fixes a bug in `MultiNormsLeafSimScorer` that assumes that each
field should have a norm for every term/document.
As part of the fix, it adds validation that the fields have consistent norms
settings.

> If some documents match but don't contain all fields, then
> {{CombinedFieldQuery}} can fail when attempting to compute norms. This is
> because {{MultiFieldNormValues}} assumes all fields in the document have
> norms.
