Add BaseTest infrastructure and diagnostic tests
Created BaseTest as foundation for all Tomcat Native tests with library initialization and comprehensive error detection for OpenSSL version mismatches and APR dependency issues. Tests fail cleanly with helpful messages when native library is unavailable. Added TestBuildEnvironment with 5 diagnostic tests for Java version verification, library path validation, and environment troubleshooting. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
