zink: more accurately track supported blits

We don't care if blits need to respect render-conditions if there's no
active one. So let's hit the potentially faster native blit-paths
instead.

Fixes: 5743fa6e709 ("zink: enable conditional rendering if available")
Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/3792
