部分安卓设备使用Vulkan FragmentDensityMap崩溃

[Liu.Wei]

Hi，

感谢提供反馈，你方便把FVulkanEXTFragmentDensityMapExtension.PostPhysicalDeviceProperties 里的GRHIVariableRateShadingImageDataType和GRHIVariableRateShadingImageFormat改成下面的格式，然后再测试一下吗？

GRHIVariableRateShadingImageDataType = VRSImage_Palette; GRHIVariableRateShadingImageFormat = PF_R8_UINT;
