anv/formats: Advertise linear sampling on depth formats

Browse source 
They've all supported it since either forever or Iron Lake which is
equivalent to forever for Vulkan.

From Kenneth Graunke's GitLab review:

    "Linear blending of depth buffer data is usually fairly nonsense
    (something's 2 meters away?  another thing's 6 meters away?  let's
    just report 4 meters?)...but it's definitely a thing we can do, so
    we may as well let apps do it, and trust them not when it doesn't
    make sense."
