NV12 Vulkan CI Errors

[cwfitzgerald]

CI is now running into after a mesa update:

Validation Error: [ VUID-VkImageCreateInfo-pNext-06722 ] | MessageID = 0x1a04b807 | vkCreateImage(): pCreateInfo->pNext<VkImageFormatListCreateInfo>.pViewFormats[0] (VK_FORMAT_R8_UNORM) and VkImageCreateInfo::format (VK_FORMAT_G8_B8R8_2PLANE_420_UNORM) are not compatible. The Vulkan spec states: If a VkImageFormatListCreateInfo structure was included in the pNext chain and VkImageFormatListCreateInfo::viewFormatCount is not zero, then each format in VkImageFormatListCreateInfo::pViewFormats must either be compatible with the format as described in the compatibility table or, if flags contains VK_IMAGE_CREATE_BLOCK_TEXEL_VIEW_COMPATIBLE_BIT, be an uncompressed format that is size-compatible with format 

Looking at this table, I don't think it's valid to pass the plane formats as view_formats. The plane functionality is similar to the existing aspect functionality used for combined depth-stencil textures where the format specified for the view is the format of one of the planes/aspects.

I think it would have made sense to add variants for the planes to TextureAspect rather than the new plane param.
