Add Vulkan‑RT hardware ray tracing support for Android Bedrock

Many modern Android flagship GPUs including Adreno 830 (Snapdragon 8 Elite) support Vulkan Ray‑Tracing extension with hardware RT‑cores. Currently Minecraft Bedrock on Android only uses OpenGL‑ES. Even devices with real ray‑tracing hardware cannot enable hardware ray tracing in‑game. Vibrant Visuals is only screen‑space simulated effect, not real hardware‑accelerated ray tracing. I suggest adding experimental Vulkan‑RT ray‑tracing support for Android RenderDragon. Keep OpenGL‑ES as fallback for old devices. So high‑end Android phones can utilize their built‑in ray‑tracing hardware, similar to DXR ray tracing on Windows Bedrock.
