📄 Description

Adding support for these clamp modes will likely require non-trivial sampler addressing emulation in shaders. For now, warn and use the closest available equivalent to enable games that use them to function.

Also set samplerMirrorClampToEdge in the Vulkan 1.2 features since it is required for using vk::SamplerAddressMode::eMirrorClampToEdge.
