This change add support VkDrmFormatModifierPropertiesList2EXT to
lavapipe driver. Previously VkDrmFormatModifierPropertiesListExt is
already supported and returns a list with one element but
VkDrmFormatModifierPropertiesList2EXT returns a empty list.

A lack of VkDrmFormatModifierPropertiesList2EXT becomes an issue
especially when the Vulkan Validation layers is enabled, it internally
uses VkDrmFormatModifierPropertiesList2EXT to confirm the
drmFormatModifierTilingFeatures is compatible to VkImageUsageFlagBits.
Without this patch it detects that the image is not compatible and
outputs warnings.
