mesh: add ComputedImplicitDestinations resource for future use (#20547)
Creates a new controller to create ComputedImplicitDestinations resources by 
composing ComputedRoutes, Services, and ComputedTrafficPermissions to 
infer all ParentRef services that could possibly send some portion of traffic to a 
Service that has at least one accessible Workload Identity. A followup PR will 
rewire the sidecar controller to make use of this new resource.

As this is a performance optimization, rather than a security feature the following 
aspects of traffic permissions have been ignored:

- DENY rules
- port rules (all ports are allowed)

Also:

- Add some v2 TestController machinery to help test complex dependency mappers.

In-Memory gRPC (#19942)
* Implement In-Process gRPC for use by controller caching/indexing

This replaces the pipe base listener implementation we were previously using. The new style CAN avoid cloning resources which our controller caching/indexing is taking advantage of to not duplicate resource objects in memory.

To maintain safety for controllers and for them to be able to modify data they get back from the cache and the resource service, the client they are presented in their runtime will be wrapped with an autogenerated client which clones request and response messages as they pass through the client.

Another sizable change in this PR is to consolidate how server specific gRPC services get registered and managed. Before this was in a bunch of different methods and it was difficult to track down how gRPC services were registered. Now its all in one place.

* Fix race in tests

* Ensure the resource service is registered to the multiplexed handler for forwarding from client agents

* Expose peer streaming on the internal handler
