Make RIM compile within memcache

Summary:
In this approach, we create a weakly defined symbol in TargetHooks.cpp that is defined in the mcrouter-core target and conditionally checked and invoked in the gen utils visitor.

This approach minimizes the amount of changes we want to make as opposed to previous approaches (most of which required making changes to hundreds of target files).

Here we do a few things to make this work:
1. In rim's stats.cpp TARGET, we have to change the odsl library to use the "via_mcrouter" flavor of those targets. autodeps wants to change it back, but that will immediately trigger circular dependencies. For good measure I added, autodeps-skip nocodemods to that target.

2. stuclar taught me about nm and how I can dump the symbols that are compiled in the different modes (dev/opt). I dumped the symbols when building mcrouter_core in both dev and opt mode and I see that gRIMReport is NOT a weak symbol, which IIUC is what we desire.

	P1430729979, P1430693327 have the full pastes.

1. I've extracted productId and plumbed it to RIM.

Remove routing hint (tech debt)

Summary:
This was an optimization we introduced for Memcache back in 2021. The idea was to pass the host returned by `getConsistentHashHost()` back to the routing layer (SR) as a "routing hint". SR could then avoid performing host selection again.

Unfortunately this optimization did not play well with failovers, and we were forced to disable it almost immediately. It was quickly forgotten and became tech debt.

I don't think there is any value in trying to rescue this optimization. The cost (in terms of engineering hours and code complexity) is probably not worth any potential gains in performance, if any. Today SR uses a dedicated uCache route handle tree, which includes a streamlined connection pool implementation, so any gains from a routing hint would be minimal or nil.
