Mason Daugherty f88d4f0212 docs(anthropic): clarify prompt caching middleware docstring (#38206 )

Updates the `AnthropicPromptCachingMiddleware` class docstring so it no
longer implies the middleware itself tags the final message tail. It
tags the system message and tool definitions and passes `cache_control`
via `model_settings`; the chat model/provider applies the message-tail
and provider-specific behavior. Docstring-only, no runtime change.
