Trimming/NativeAOT support

[HavenDV]

According this article: https://learn.microsoft.com/en-us/dotnet/core/deploying/trimming/prepare-libraries-for-trimming?pivots=dotnet-8-0

Now there are such warnings:

1>InternalListHelpers.cs(34,9): Warning IL2091 Trim analysis: OpenAI.InternalListHelpers.GetPageFromProtocol<TInstance,UInternalList>(ClientResult): 'T' generic argument does not satisfy 'DynamicallyAccessedMemberTypes.PublicConstructors', 'DynamicallyAccessedMemberTypes.NonPublicConstructors' in 'System.ClientModel.Primitives.ModelReaderWriter.Read<T>(BinaryData, ModelReaderWriterOptions)'. The generic parameter 'UInternalList' of 'OpenAI.InternalListHelpers.GetPageFromProtocol<TInstance,UInternalList>(ClientResult)' does not have matching annotations. The source value must declare at least the same requirements as those declared on the target location it is assigned to.
1>System.Memory.Data.dll: Warning IL2104 : Assembly 'System.Memory.Data' produced trim warnings. For more information see https://aka.ms/dotnet-illink/libraries

If I use the preview version of System.Memory.Data, the following warnings appear here

1>ModerationClient.cs(77,9): Warning IL2026 Trim analysis: OpenAI.Moderations.ModerationClient.<ClassifyTextInputAsync>d__4.MoveNext(): Using member 'System.BinaryData.FromObjectAsJson<T>(T, JsonSerializerOptions)' which has 'RequiresUnreferencedCodeAttribute' can break functionality when trimming application code.

@HavenDV, thanks for the prompt discovery of this and even getting a comprehensive change prepared! Trimming support is a topic under investigation with the System.ClientModel team (where the result collections originate from) and we'll follow up ASAP based on that conversation.
