.Net: ChatSettings Support

[rogerbarreto]

Allow a ChatOptions to be sent via PromptExecutionSettings.

This feature will allow ChatOptions abstraction to be passed as a specialized version of PromptExecutionSettings that can be handled as a proxy by ChatClientCompletionService internally, allowing scenarios that require passing customized ChatOptions configurations from KernelFunctions and Kernel invoke methods.

This feature will allow, all the flexibilities of the ChatOptions like: "Additional properties", "RawRepresentationFactory", "Instructions", etc to be used by the invoked ChatClients.
