Ref T13000. This adds support for tracking "common" ngrams, which occur in too many documents to be useful as part of the ngram index.
If an ngram is listed in the "common" table, it won't be written when indexing documents, or queried for when searching for them.
In this change, nothing actually writes to the "common" table. I'll start writing to the table in a followup change.
Specifically, I plan to do this:
- A new GC process updates the "common" table periodically, by writing ngrams which appear in more than X% of documents to it, for some value of X, if there are at least a minimum number of documents (maybe like 4,000).
- A new GC process deletes ngrams that have been added to the common table from the existing indexes.
Hopefully, this will pare down the ngrams index to something reasonable over time without requiring any manual tuning.
Test Plan:
- Ran some queries and indexes.
- Manually inserted ngrams `xxx` and `yyy` into the ngrams table, searched and indexed, saw them ignored as viable ngrams for search/index.

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.

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.

- I'm making these one-to-one, more or less: an issue can't be bridged to a bunch of tasks, nor can a bunch of tasks be bridged to a single issue. Pretty sure this makes sense?

- The workspace cache is stored at each query, so adjacent queries can't benefit from the cache (only subqueries). Feed has primarily sibling queries.
- There is no technical reason to do this. Store the workspace cache on the root query, so sibling queries can hit it.
- In `ObjectQuery`, we check the workspace once, then load all the PHIDs. When the PHIDs are a mixture of transactions and objects, we always miss the workspace and load the objects twice.
- Instead, check the workspace after loading each type of object.
- `HandleQuery` does not set itself as the parent query for `ObjectQuery`, so handles never hit the workspace cache.
- Pass it, so they can hit the workspace cache.
- Feed's weird `PhabricatorFeedStory::loadAllFromRows()` method does not specify a parent query on its object/handle queries.

Summary:
Ref T8575. Because orderable columns need to build custom fields, they are relatively expensive to build. Use the request cache.
(The request cache is technically more correct than `static`, because configuration may change between requests and we may eventually reuse interpreters.)
Test Plan: Saw home page time drop 39% (from 462ms to 283ms).
