Fix(build): Use standard CMake pipelines and clean up dev package

- Replaced custom build steps with Melange standard CMake pipelines (configure, build, install).
- Set BUILD_TESTING=OFF as want_check was causing issues.
- Removed manual handling of aws-c-auth dev folder, as it is now managed upstream (see: awslabs/aws-c-auth#258).
