[jeremystretch]

Closes: #10560

• Introduce CachedValue model to store cached model field values for search
• Introduce an indexer class for all searchable models, specifying fields and their weights ($app/search.py)
• Introduce the reindex management command to [re]build the cache
• Implement table-based search results with HTMX
• Add search_weight field to CustomField model
• Remove legacy search backend
• Remove object type selector from UI search bar
• Replace search_options template tag with inclusion template (inc/searchbar.html)
• Introduce RestrictedGenericForeignKey and RestrictedPrefetch to enable restricting pre-fetched GFK objects based on user permissions

The following instances of bulk_create and bulk_update should probably be changed to normal saving, otherwise signals are not sent.

This should probably have been done anyway, as changelogs are not created currently for these objects. It will make those operations significally slower though, not sure if there's a fast way to bulk create and fire off signals in django, I'm guessing you would have to override bulk_create and bulk_update to send the signals manually after successful insert/update.

@kkthxbye-code that's a very good observation. We've had a de facto ban on bulk_create() and bulk_update() outside of tests and migrations for a long time for precisely this reason. I think their use for replicating device components has been ignored until now because the absence of change logs for these actions hasn't been impactful, but you're correct that this needs to change. I've opened housekeeping issue #10694 to capture this.

Need to figure out why we have a test failing under Python 3.9+.
