LUCENE-9446: In boolean rewrite, remove MatchAllDocsQuery filter clauses (#1709)
Previously, we only removed 'match all' FILTER clauses if there was at least one
MUST clause. Now they're also removed if there is another distinct FILTER
clause.
This lets boolean queries like `#field:value #*:*` be written to `#field:value`.
> Boolean rewrite could remove more MatchAllDocsQuery filters

> It seems that BooleanQuery rewrites will remove a MatchAllDocsQuery 'filter'
> clause only if there is at least one 'must' clause. I think we could also
> remove the 'filter' clause if there are no 'must' clauses, but at least one
> other 'filter' clause.
> This could let queries like {{#field:value #*:*}} be rewritten to
> {{#field:value}}.
