Summary:
See brief discussion in D18554. All the index tables are the same for every application (and, at this point, seem unlikely to change) and we never actually pass these objects around (they're only used internally).
In some other cases (like Transactions) not every application has the same tables (for example, Differential has extra field for inline comments), and/or we pass the objects around (lots of stuff uses `$xactions` directly).
However, in this case, and in Edges, we don't interact with any representation of the database state directly in much of the code, and it doesn't change from application to application.
Just automatically define document, field, and ngram tables for anything which implements `FerretInterface`. This makes the query and index logic a tiny bit messier but lets us delete a ton of boilerplate classes.
Test Plan: Indexed objects, searched for objects. Same results as before with much less code. Ran `bin/storage upgrade`, got a clean bill of health.

Summary:
Ref T12819. I started trying to get individual engines to drive these constraints (e.g., `ManiphestTaskQuery` can do most of the work) but this is a big pain, especially since most engines don't support "any owner" or "no owner", and not everything has an owner, and so on and so on. Going down this path would have meant a huge pile of stub functions everywhere, I think.
Instead, drive these through the main engine using the fulltext document table, which already has everything we need to apply these constraints in a uniform way.
Also tweak some parts of query construction and result ordering.
Test Plan: Searched for documents by author, owner, unowned, any owner, tags, subscribers, fulltext in global search. Got sensible results without any application-specific code.

Summary:
Ref T12819. Provides a Ferret-engine-based fulltext engine to ultimately replace the InnoDB fulltext engine.
This is still pretty basic (hard-coded and buggy) but technically sort of works.
To activate this, you must explicitly configure it, so it isn't visible to users yet.
Test Plan: Searched for objects with global fulltext search, got a mixture of matching revisions and tasks back.

Summary: Ref T12819. Move these out of the core engine into the Ferret engine. In the future different applications can define different functions, like "summary:..." or whatever. This may get more formalization when I possibly do "author:" and such some time down the road.
Test Plan: Searched for "title:...". Searched for "dog:...", got a useful error.

Summary:
Ref T12819. I gave this stuff a sweet code name because all the terms related to "fulltext" and "search" already mean 5 different things. It, uh, ferrets out documents for you?
I'm building this to work a lot like the existing ngram index, which seems to work pretty well. If this sticks, it will auto-resolve the join issue (in T12443) by letting us do the entire thing locally in a JOIN and thus dodge a lot of mess.
This index gets built alongside other indexes, but only shows up in the UI if you have prototypes enabled. If you do, it appears under the existing fulltext field in Maniphest. No existing functionality is affected or disrupted.
NOTE: The query engine half of this is still EXTREMELY primitive, and this probably performs worse than the existing field for now. If this doesn't show obvious signs of being awful on `secure` I'll improve that in followup changes.
Test Plan:
Indexed my tasks, ran some simple queries, got the results I wanted, even for queries "ko", "k", "v0.1".
