SOLR-12368: inplace update for field that doesn't yet exist in any doc
If the field is non-stored, non-indexed and docvalue enabled numeric field
then inplace update can be done. previously, lucene didn't support
docvalue update for field that is not yet present in indexWriter but
LUCENE-8316 added support for this.
This adds support to update field which satisfies inplace conditions
but which doesn't yet exist in any docs
> in-place DV updates should no longer have to jump through hoops if field does
> not yet exist

> When SOLR-5944 first added "in-place" DocValue updates to Solr, one of the
> edge cases thta had to be dealt with was the limitation imposed by
> IndexWriter that docValues could only be updated if they already existed - if
> a shard did not yet have a document w/a value in the field where the update
> was attempted, we would get an error.
> LUCENE-8316 seems to have removed this error, which i believe means we can
> simplify & speed up some of the checks in Solr, and support this situation as
> well, rather then falling back on full "read stored fields & reindex" atomic
> update
