Summary:
I'm about 90% sure this fixes the intermittent test failure on `testObjectSubscribersPolicyRule()` or whatever.
We use `spl_object_hash()` to identify objects when passing hints about policy changes to policy rules. This is hacky, and I think it's the source of the unit test issue.
Specifically, `spl_object_hash()` is approximately just returning the memory address of the object, and two objects can occasionally use the same memory address (one gets garbage collected; another uses the same memory).
If I replace `spl_object_hash()` with a static value like "zebra", the test failure reproduces.
Instead, sneak an object ID onto a runtime property. This is at least as hacky but shouldn't suffer from the same intermittent failure.
Test Plan: Ran `arc unit --everything`, but I never got a reliable repro of the issue in the first place, so who knows.

Summary:
Ref T11954. This is kind of complex and I'm not sure I want to actually land it, but it gives us a fairly good improvement for clustered repositories so I'm leaning toward moving forward.
When we make (or receive) clustered repository requests, we must first load a bunch of stuff out of Almanac to figure out where to send the request (or if we can handle the request ourselves).
This involves several round trip queries into Almanac (service, device, interfaces, bindings, properties) and generally is fairly slow/expensive. The actual data we get out of it is just a list of URIs.
Caching this would be very easy, except that invalidating the cache is difficult, since editing any binding, property, interface, or device may invalidate the cache for indirectly connected services and repositories.
To address this, introduce `PhabricatorCacheEngine`, which is an extensible engine like `PhabricatorDestructionEngine` for propagating cache updates. It has two modes:
- Discover linked objects (that is: find related objects which may need to have caches invalidated).
- Invalidate caches (that is: nuke any caches which need to be nuked).
Both modes are extensible, so third-party code can build repository-dependent caches or whatever. This may be overkill but even if Almanac is the only thing we use it for it feels like a fairly clean solution to the problem.
With `CacheEngine`, make any edit to Almanac stuff propagate up to the Service, and then from the Service to any linked Repositories.
Once we hit repositories, invalidate their caches when Almanac changes.
Test Plan:
- Observed a 20-30ms performance improvement with `ab -n 100`.
- (The main page making Conduit calls also gets a performance improvement, although that's a little trickier to measure directly.)
- Added debugging code to the cache engine stuff to observe the linking and invalidation phases.
- Made invalidation throw; verified that editing properties, bindings, etc, properly invalidates the cache of any indirectly linked repositories.

Ref T11954. This reduces how much work we need to do to load settings, particularly for Conduit (which currently can not benefit directly from the user cache, because it loads the user indirectly via a token).
Specifically:
- Cache builtin defaults in the runtime cache. This means Phabricator may need to be restarted if you change a global setting default, but this is exceptionally rare.
- Cache global defaults in the mutable cache. This means we do less work to load them.
- Avoid loading settings classes if we don't have to.
- If we missed the user cache for settings, try to read it from the cache table before we actually go regenerate it (we miss on Conduit pathways).

Ref T11954. Depends on D16993. We have a couple of "look up the class for this key" queries which are costly enough to show up on a profile.
These aren't huge wins, but they're pretty easy. We currently do this like this:

return idx($class_map, $key);
```
However, we don't need to load EVERY subclass if we're only looking for, say, the Conduit method subclass which implements `user.whoami`. This allows us to cache that map and find the right class efficiently.
This cache is self-validating and completely safe even in development.
Test Plan:
- Used `curl` to make queries to `user.whoami`, verified that content was identical before and after the change.
- Used `ab -n100` to roughly measure 99th percentile time, which dropped from 74ms to 65ms. This is a small improvement (13% in the best case, here) but it benefits every Conduit method call.

Ref T11954. Depends on D16992. We have some data which can be generated and cached at runtime. Three examples are:
- Class map from Conduit method names to implementing classes.
- Class map from PHID types to implementing classes.
- The main routing map.
None of these are huge wins but they impose global costs and can be shaved down through caching without introducing an enormous amount of new complexity.
The cost to these maps is that sometimes you'll need to restart your webserver, even in development mode if these caches are active. However, in some cases these changes are very rare, and in other cases we can just leave the cache disabled in development mode without a huge complexity cost.
Specifically, the Conduit/PHID type class maps are self-validating and can not go bad, even in development mode.
The routing map will be able to, but I plan to just disable it in development mode.
This provides a general-purpose pure APC cache stack for storing this data.

However, if we don't warn users about this they'll just get a broken index unless they go read the changelog (or file an issue, then we tell them to go read the changelog).
This adds a very simple table for notes to administrators so we can write a "you need to go rebuild the index" note, then adds one.
Administrators clear the note by completing the activity and running `bin/config done reindex`. This isn't automatic because there are various strategies you can use to approach the issue, which I'll discuss in greater detail in the linked documentation.
