With this change, DDS takes responsibility for service extension
registration via the service protocol in addition to handling service
extension request routing.
Service extensions registered through dart:developer will continue to
be handled by the VM service as those extensions live within the main
Dart process (this functionality already worked before this CL).
This change also includes a version bump for package:json_rpc_2 to pull
in a bug fix required for this change.

Added a private RPC, _yieldControlToDDS, which DDS invokes once
connected to the VM service. Once this method is called, the following
happens:
- The VM service stops accepting new web socket requests.
- The VM service enters single client mode, where DDS is the single
client.
DDS can only place the VM service in single client mode when it is the only
VM service client. If other clients are connected, DDS will fail to start and
throw an exception.
The purpose of this change is to simplify state management between the
VM service and DDS. The plan is to delegate the following features to
DDS:
- Service extension management
- Custom client name support
- Isolate resume coordination for multiple clients

Original change's description:
> [ Service / package:dds ] Add stream support to package:dds and enable DDS for VM service tests
>
> This change adds stream forwarding to the Dart Development Service,
> allowing for clients to subscribe to service protocol streams with DDS
> instead of the VM service directly. DDS will maintain a single
> subscription for each stream as long as at least one client is listening
> to that stream. A DDS stream subscription will be closed when the last
> client listening to that stream either disconnects or calls
> streamCancel.
>
> This change also enables DDS for most of the Observatory services tests,
> excluding thoses which utilize:
>
> - Service extensions
> - Client naming
> - Client isolate resume synchronization
