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 Change-Id: I0b3143710d94ee9444a4894e24555f7ed1caf5ad Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/142564 Commit-Queue: Ben Konyi <bkonyi@google.com> Reviewed-by: Ryan Macnak <rmacnak@google.com>
