Remove legacy "touched" table and indexing

Summary: Noticed this in the schema. "Touches" were an idea that never really got off the ground, as we built out more/better notification channels instead. Essentially, they recorded any object you'd ever interacted with. Maybe this will be useful some day, but for now it does nothing and can't be interacted with. Nuke it.

Test Plan: `grep`, loaded Maniphest.

Index projects in the main search index

Summary:
Part one of a large and complicated plot:

  - The last filter for Maniphest "pro" queries is "Group By".
  - This is currently executed in a convoluted and ridiculous way, loading massive amounts of data.
  - The primary reason it works like it does is that we don't have a project name index available in Maniphest, so we can't sort in the DB.
  - So, I want to provide a name index to Maniphest and push this work to the DB.

To do that, my plan is:

  - Index projects in Search.
  - Add a "did update index" event.
  - Have Maniphest listen for it.
  - When projects are updated, update their indexes in Maniphest.
  - Rewrite the giant mess of "group by: project" to be somewhat reasonable.
  - This may also extend to some future "group by: assignee".

This is the first small step down this path, which just indexes projects in search.

Test Plan: Ran `bin/search index --type project`, then searched for projects.

Add event dispatch for updated search indexes

Summary:
See discussion in D6955. Provide an event for applications and users to update secondary search indexes.

Facebook: I don't recall exactly how all the search stuff is rigged up, but this might provide a more practical / less fragile alternative. I think it publishes into ElasticSearch now, and then intern somehow handles the result merge at display time, implictly relying on Phabricator's storage format? A cleaner approach might be to publish a secondary "intern" index in a standard format.

Test Plan: Ran `bin/search index --type proj --trace`, saw events fire.

Provide and populate an object name index for Maniphest

Summary: See discussion in D6955. This provides a table we can JOIN against to (effectively) "ORDER BY project name", populates it intially, and keeps it up to date as projects are edited.

Test Plan:
  - Ran storage upgrade, verified projects populated into the table.
  - Edited a project, verified its entry updated.

Service "Group by: Project" in Maniphest out of a local index

Summary:
See discussion in D6955. Currently, the logic for "Group by: Project" is roughly:

  - Load every possible result.
  - Lots of in-process garbage.

Instead, use the new local project name index (from D6957) to service this query more reasonably. Basically:

  - Join a table which has keyed project names.
  - Order by that table.

Test Plan: {F58033}

Call array_unique() in Handle/Object queries

Summary: I think the old thing did this, but this makes queries a bit less ridiculous. For example, `secure.phabricator.com` currently issues a query for 664 handles on my task list, but only 73 of them are unique (basically, all the projects plus all the authors). This proably is slightly good for performance, but mostly makes the "Services" tab manageable.

Test Plan: Looked at Maniphest and some other pages, saw handles and objects where they were expected to be.
