use crate TypedBuilder for builders

[HJLebbink]

This PR migrates from hand-rolled builder structs to the TypedBuilder crate, implementing a standardized builder pattern across the entire S3 client library. This change introduces the .build() method call requirement for all request builders while maintaining the existing API surface.

Adopts TypedBuilder for consistent, type-safe builder patterns across all S3 operations
Updates all client methods to return TypedBuilder-generated builder types
Adds required .build() calls to all test files for new builder API
