Improve python wrapper generation

- Add "BUILD_PACKAGE" option that is OFF by default (CI issues)

- Optionally package wrapper if python3.7 or above is present (hack for CI)
- Optionally build wrapper if clang is present (hack for CI)
- Improve dependency resolution for wrapper
- Use python venv
- Use pyproject.toml instead of setup.py
- Use CMake install path to search for libamd_smi.so
- Move python-specific CMakeLists into py-interface
- Search for libamd_smi.so more aggressively
