• Round 2 of cleanup for agent runtime and orchestrations (#164)

  - Moved InProcessRuntime type into abstractions package and deleted InProcess package.
  - Moved several members of IAgentRuntime to be extension methods instead, e.g. multiple GetActorAsync overloads.
  - Added synchronous RegisterMessageHandler overloads and used them to avoid unnecessary async usage at call sites.
  - Removed unnecessary surface area from InProcessRuntime, e.g. StopAsync, RunUntilIdleAsync, etc.
  - Fixed spin loop in InProcessRuntime that would consume an entire core for the duration of the orchestration's operation.
  - Removed a bunch of allocation from InProcessRuntime.
  - Made a runtime optional for orchestrations, defaulting to using a temporary InProcessRuntime if none is provided.
  - Removed custom delegate types from orchestrations.
  - Consolidated namespaces.
  - Used records to simplify message classes.
  - Tweaked naming on AgentActor to make purpose of protected methods more clear.
  - Removed invocation in AgentActor.InvokeAsync of empty update / isFinal parameter.
  - Changed OrchestrationHandoffs to avoid needing to pass in agents duplicatively.
  - Made various extension methods, such as those on OrchestrationHandoffsExtensions, into instance methods.
