Update CI workflow for Windows builds and refactor room object handling

- Modified the CI workflow to conditionally set up vcpkg and configure CMake based on the build type for Windows, enhancing build flexibility.
- Refactored the handling of staircase objects in the Room class to use initializer lists for improved clarity and consistency in object construction.
- Updated chest data handling to utilize modern C++ syntax for better readability.
