Implements Anthropic's prompt caching feature to improve token efficiency.

- Adds cache control support in AnthropicApi and AnthropicChatModel
- Creates AnthropicCacheType enum with EPHEMERAL cache type
- Extends AbstractMessage and UserMessage to support cache parameters
- Updates Usage tracking to include cache-related token metrics
- Adds integration test to verify prompt caching functionality

This implementation follows Anthropic's prompt caching API (beta-2024-07-31) which allows
for more efficient token usage by caching frequently used prompts.

@Claudio-code Something doesn't look right with the PR. The PR contains a few unrelated commits. Could you rebase your PR branch against the latest main and then add the changes related to the anthropic prompt caching as a single commit on top? Make sure to use DCO on that commit. Thanks!

@Claudio-code Claudio-code Can you squash the relevant commits for prompt caching into a single commit? Please remove all the other commits. I am having difficulty rebasing your PR to the latest main. It would make things easier on our end to review the PR. Thanks!
