Samuel Pitoiset 7b70502a5d radv: implement VK_AMD_mixed_attachment_samples
With VK_AMD_mixed_attachment_samples, the number of depth/stencil
samples isn't always equal to the number of color samples. Adjust
the number of Z samples when it's different but make sure to have
a consistent sample count if there are no depth/stencil attachments.

Also adjust the number of samples used for fragment shaders which is
the number of color samples if mixed attachment samples are used.

Only enabled on GFX8+ because it's untested on previous chips.

All dEQP-VK.pipeline.multisample.mixed_attachment_samples.* now pass.
