Book Page: Other Editions Table → Solr

### Describe the problem that you'd like solved

Today, the "Other Editions" table is one of the most expensive parts to load of our Book Page, which is one of our more important pages; see: #6195. There are two main reasons for this:

1. It requires we fetch lots of records from infogami
2. It requires we fetch Bulk Book Availability info for these items

The table has other issues. Most patrons likely only want readable books in the list. But to determine this (without solr) we need to fetch more than we need from infogami. This results in issues like #7233

### Proposal & Constraints

This issue proposes we:
1. switch the Other Editions table to use Solr Editions instead of infogami
2. update the search function so it also uses Solr (solving #7233)
3. Get a further win by pairing this issue with #7450 (to remove the Bulk Availability check)
