[Mesa-stable] [PATCH] anv/format: handle unsupported formats properly

[Iago Toral Quiroga]

According to the spec for vkGetPhysicalDeviceImageFormatProperties:

"If format is not a supported image format, or if the combination of format,
 type, tiling, usage, and flags is not supported for images, then
 vkGetPhysicalDeviceImageFormatProperties returns VK_ERROR_FORMAT_NOT_SUPPORTED."

Makes the following Vulkan CTS tests report 'Not Supported' instead of crashing:

dEQP-VK.api.image_clearing.clear_color_image.1d_b8g8r8_unorm
dEQP-VK.api.image_clearing.clear_color_image.1d_b8g8r8_snorm
