ci: enforce clippy in examples folder

[wmmc88]

This pull request introduces improved error handling and context for file system operations in the wdk-build crate, refactors path validation logic for include and library directories, and updates the CI workflow to lint example projects using Cargo Make. The most important changes are grouped below:

Error Handling Improvements

• Introduced new types IoError and IoErrorMetadata to wrap std::io::Error with additional context about the file system paths involved in I/O failures, and updated ConfigError to use these types for better diagnostics. [1] [2]
• Refactored file system operations throughout crates/wdk-build/src/cargo_make.rs and related code to use the new error types, providing richer error information for failures in directory creation, file copying, symlink creation, and path canonicalization. [1] [2] [3] [4] [5]

Path Validation Refactoring

• Consolidated directory existence and canonicalization logic into a new helper method validate_and_add_include_path, reducing code duplication and ensuring consistent error reporting for include and library paths in the Config struct. [1] [2] [3] [4] [5]

CI Workflow Enhancement

• Updated .github/workflows/lint.yaml to install Cargo Make and add a linting step for example projects using cargo make clippy, ensuring that example code is checked for lint issues in CI.

Minor Codebase Improvements

• Updated imports in crates/wdk-build/src/lib.rs to include new types and paths required for enhanced error handling.
• Simplified error propagation for header file lookup by removing unnecessary error mapping in ucx_header.
