Make Microsoft.Agents.Builder.TurnContext.BufferedReplyActivities public

Is your feature request related to a problem? Please describe.

In the Agents SDK BufferedReplyActivities has been made internal, however adapters (custom or otherwise) without a proactive messaging facility need access to this to respond with the activities generated by the incoming request.

Agents-for-net/src/libraries/Builder/Microsoft.Agents.Builder/TurnContext.cs

Line 127 in 7476b1e

internal List<IActivity> BufferedReplyActivities { get; } = new List<IActivity>();

It was previously public in BF TurnContext.cs#L149

Describe the solution you'd like
Make BufferedReplyActivities public.

Describe alternatives you've considered
The alternative is a custom implementation of ITurnContext, however it is such key piece of the the SDK that a custom implementation is a last resort.

@joetossell So the scenario is you want a custom Adapter, say from ChannelAdapter, but want to support DeliveryModes.ExpectReplies, correct?

[joetossell]

@tracyboehrer this is correct, a custom Adapter, inheriting from ChannelAdapter or IChannelAdapter, where DeliveryModes.ExpectReplies is set to allow the adapter to send the replies in the response to the initial request where proactive messaging is not supported.

@joetossell Reviewing this over the next few days. Originally, this was public, but I had this loose thought about refactoring how ExpectReplies and the new DeliveryMode.Stream is handled. But that didn't happen, and at this point may be difficult to change.
