radv: emit correct last export when Z/stencil export is enabled
I was getting a random GPU hang in the renderpass simple tests,
it turns out sometimes radv emitted the wrong thing "last".
This fixes the logic to emit Z/stencil last if they occur,
and not mark a color output as last. Also this relies on the
Z/STENCIL being the first two fragment outputs, which they are
so yay.
Fixes: dEQP-VK.renderpass.simple.color_depth (random hangs)
