We would like draw-only display lists to have immutable draw info and
this is the only GL non-draw state in pipe_draw_info (not counting
view_mask).
It also allows removing some code from draw_vbo for tessellation.

We often do this:
pipe->set_constant_buffer(pipe, shader, slot, &cb);
pipe_resource_reference(&cb->buffer, NULL);
That results in atomic increment in set_constant_buffer followed by
atomic decrement after set_constant_buffer. This new interface
eliminates those atomics.
For the case above, this should be used instead:
pipe->set_constant_buffer(pipe, shader, slot, true, &cb);
cb->buffer = NULL; // if cb is not a local variable, else do nothing
AMD Zen benefits from this. The perf improvement is ~3% for Viewperf13/Catia.

The vulkan cond rendering hook is quite different than the
traditional gallium one so add a new interface for it.
This just conditionalises rendering on the memory location.
