fixed to behave like a `Client` when the connection is closed with
outstanding requests.
`package:dds` was previously relying on having the futures never
complete to send the `serviceDisappeared` code when the client was
closed with outstanding requests. Check also for the `StateError` that
would result from outstanding requests and translate them to
`serviceDisappeared`.

Final cleanup work before first full version of package:dds is
published:
- Added `getSupportedProtocols` RPC to the VM service protocol, which returns a
list of supported service protocols and extensions along with their version
information.
- Added `getDartDevelopmentServiceVersion` RPC to the DDS protocol.
- Misc code and dependency cleanup recommended by pub

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
