Subject: Add command-line arguments to examples (#7835)

* Add command-line arguments to triangle example

- Add -h/--help flag to show usage information
- Add -api flag to select rendering API (d3d11 < /dev/null | d3d12|vulkan|metal|cpu|cuda|webgpu)
- Platform-specific API availability (D3D on Windows, Metal on macOS)
- Output works for both console and WIN32 applications
