Corentin Wallez 8e68a89cfb Vulkan: Clamp @builtin(frag_depth) with push constant values
Start using Tint's ClampFragDepth transform in the Vulkan backend when
needed in order to correctly clamp @builtin(frag_depth) on Vulkan. Do
this by always reserving 8 bytes of push constant space to contain the
f32 min and max values from the last viewport command.

Reenables relevant CTS tests that were suppressed on Vulkan.
