a9f9953928 docs/gallium: Note samplers are not used for txf 
Now that PIPE_CAP_TEXTURE_BUFFER_SAMPLER is gone, txf does not require samplers
for any texture on any Gallium driver. NIR already requires drivers to ignore
sampler_index for non-sampler operation (mainly txf), and nowadays all Gallium
drivers ingest NIR. So, document that samplers aren't bound for txf (etc) as
part of the Gallium frontend-driver contract.

6ba29d37c8 gallium: Remove PIPE_CAP_TEXTURE_BUFFER_SAMPLER 
No more users. It was already not respected by rusticl so you couldn't set it if
you wanted OpenCL support. I regret introducing the CAP in the first place, and
no more drivers should use it.

10a46226b1 gallium: remove vertices_per_patch, add pipe_context::set_patch_vertices 
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.

a51d4b10f1 gallium: add take_ownership param into set_constant_buffer to eliminate atomics 
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.

86328fc7b7 gallium: add a cond rendering hook for vulkan. 
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.
