anv: fix viewport transformation for z component
In Vulkan, for 'z' (depth) component, the scale and translate values
for the viewport transformation are:
pz = maxDepth - minDepth
oz = minDepth
zf = pz × zd + oz
Being zd, the third component in vertex's normalized device coordinates.
Fixes: dEQP-VK.draw.inverted_depth_ranges.*
