vulkan: physical device does not support DRM format modifiers

VK_EXT_image_drm_format_modifier is required for importing image from dma buf that contains modifiers.

NV proprietary, Intel ANV and RADV have supported this for a while.

Since these two related extensions have been supported in AMDVLK, it'd be great if we can have modifier support.

VK_EXT_external_memory_dma_buf
VK_KHR_external_memory_fd

Thanks!

We have been working on the extension.

@jinjianrong Nice to hear that! Any plans on adding modifier in KMD for gfx8 Polaris? This generation still has a wide user base, but due to the big difference from gfx9, developers from Google only added modifier support for gfx9+.
