This PR implements performance optimizations across the MinIO Rust SDK, focusing on reducing latency and improving throughput for high-performance use cases like DataFusion/ObjectStore integration. Key improvements include signing key caching, HTTP/2 optimization, region lookup bypass, and fast-path APIs.
Key Changes:
Performance optimizations: Signing key caching (4 HMAC ops saved per request), HTTP/2 adaptive window, optimized query/header string building, and a fast-path GET API
Bug fixes: Corrected multipart copy logic, changed stat_object to use HEAD method, fixed region handling in tests
API enhancements: Added get_object_fast(), into_boxed_stream(), and into_bytes() methods for high-performance scenarios
Adds RequestHooks trait to enable intercepting and modifying S3 API
requests at key points in the request lifecycle. This enables implementing
cross-cutting concerns like load balancing, telemetry, and debug logging
without modifying the core request handling logic.

- Update all X-Amz-* headers to use capital letters after hyphens (e.g., X-Amz-Date)
- Update standard HTTP headers to use proper case (e.g., If-Modified-Since)
- Update X-Minio headers to follow same capitalization pattern
- Aligns with AWS S3 API specification and HTTP standards
