synapse: embedding a Track1 Data Plane SDK

[tombuildsstuff]

This PR embeds an Azure SDK for Go Track1 Data Plane SDK for Azure Synapse, so that those Data Plane resources can be built out. This client can be built as such:

func (client Client) Workspaces(workspaceName, synapseEndpointSuffix string) (*artifacts.WorkspaceClient, error) {
       if client.synapseAuthorizer == nil {
               return nil, fmt.Errorf("Synapse is not supported in this Azure Environment")
       }
       endpoint := buildEndpoint(workspaceName, synapseEndpointSuffix)
       workspacesClient := artifacts.NewWorkspaceClient(endpoint)
       workspacesClient.Client.Authorizer = client.synapseAuthorizer
       return &workspacesClient, nil
}

But notably the Data Plane API requires that a firewall rule be added for the IP address being used - as such this will either need to be a prerequisite, or added/removed dynamically - neither's great, but I'll leave that for the implementer of these data plane resources to work out.

Generated based on this upstream Swagger PR: Azure/azure-rest-api-specs#15263 - with one minor change to remove some incorrectly output "": autorest.Encode("path"), (since these are unnecessary)
