Subject: [PATCH 1/3] feat: add GPU acceleration JVM parameters support

- Add Prism rendering pipeline parameters when enable_gpu_acceleration is enabled
- Windows: -Dprism.order=d3d,es2,sw (Direct3D priority)
- Linux/macOS: -Dprism.order=es2,sw (OpenGL ES priority)
- Add -Dprism.forcegpu=true to force hardware acceleration
