anv: FORMAT_FEATURE_TRANSFER_SRC/DST_BIT_KHR not used with VkFormatProperties.bufferFeatures

Browse Source 
VK_FORMAT_FEATURE_TRANSFER_[SRC|DST]_BIT_KHR is a flag value of the
VkFormatFeatureFlagBits enum that can only be hold and checked against
the linearTilingFeatures or optimalTilingFeatures members of the
VkFormatProperties struct but not the bufferFeatures member.

>From the Vulkan® 1.0.51, with the VK_KHR_maintenance1 extension,
section 32.3.2 docs for VkFormatProperties:

   "* linearTilingFeatures is a bitmask of VkFormatFeatureFlagBits
      specifying features supported by images created with a tiling
      parameter of VK_IMAGE_TILING_LINEAR.

    * optimalTilingFeatures is a bitmask of VkFormatFeatureFlagBits
      specifying features supported by images created with a tiling
      parameter of VK_IMAGE_TILING_OPTIMAL.

    * bufferFeatures is a bitmask of VkFormatFeatureFlagBits
      specifying features supported by buffers."

    ...

    Bits which can be set in the VkFormatProperties features
    linearTilingFeatures, optimalTilingFeatures, and bufferFeatures
    are:

    typedef enum VkFormatFeatureFlagBits {

    ...

      VK_FORMAT_FEATURE_TRANSFER_SRC_BIT_KHR = 0x00004000,
      VK_FORMAT_FEATURE_TRANSFER_DST_BIT_KHR = 0x00008000,

    ...

    } VkFormatFeatureFlagBits;

    ...

    The following bits may be set in linearTilingFeatures and
    optimalTilingFeatures, specifying that the features are supported
    by images or image views created with the queried
    vkGetPhysicalDeviceFormatProperties::format:

    ...

    * VK_FORMAT_FEATURE_TRANSFER_SRC_BIT_KHR specifies that an image
      can be used as a source image for copy commands.

    * VK_FORMAT_FEATURE_TRANSFER_DST_BIT_KHR specifies that an image
      can be used as a destination image for copy commands and clear
      commands."
