Plumb binder from proxy

Summary:
This creates the BnSharedActivityApi instance in the proxy impl and plumbs it to the CallProviderService. This will then allow clients to get the API when they bind to the CallProviderService.

The ISharedActivityApi is just a skeleton for now and will be filled in over time.
