Document strategies to handle invalid tool input

[verdie-g]

Describe the issue or suggestion

A LLM can provide invalid input when request tool calls. In this discussion with Stephen, several strategies were mentioned to deal with that.

The documentation could be improved with:

• FunctionInvokingChatClient.IncludeDetailedErrors to send serialization (and other) exceptions back to the LLM
• FunctionInvokingChatClient.FunctionInvoker to, for example, catch serialization exceptions. It could also be interesting to document that it can be used to implement a retry mechanism, like throwing a MyRetryException from a tool (because of incoherent input or something), catching it in the FunctionInvoker and returning a message to make the LLM retry "invalid something, please retry". Sharing good prompts that make some models retry a tool call would be a plus.
• strictJsonSchema special property for OpenAI
