27dcb46629 gallium: add take_ownership param into set_vertex_buffers to eliminate atomics
There are a few places (mainly u_threaded_context) that do:
   set_vertex_buffers(...);
   for (i = 0; i < count; i++)
      pipe_resource_reference(&buffers[i].resource.buffer, NULL);

set_vertex_buffers increments the reference counts while the loop
decrements them.

This commit eliminates those reference count changes by adding a parameter
into set_vertex_buffers that tells the callee to accept all buffers
without incrementing the reference counts.

AMD Zen benefits from this because it has slow atomics if they come from
different CCXs.

b688ea31fc gallium: add unbind_num_trailing_slots to set_sampler_views
Instead of calling this functions again to unbind trailing slots,
extend it to do it when binding. This reduces CPU overhead.

A lot of drivers ignore "start" and always unbind all slots after "count".
Such drivers don't need any changes here.

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.

68d70fb969 gallium: Add format modifier plane count query
Rather than hard-code a list of all the format
modifiers supported by any gallium driver and the
number of aux planes they require in the dri state
tracker, add a screen proc that queries the number
of planes required for a given modifier+format
pair.

Since the only format modifiers that require
auxiliary planes currently are the iris driver's
I915_FORMAT_MOD_Y_TILED_CCS,
I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS, and
I915_FORMAT_MOD_Y_TILED_GEN12_MC_CCS, the absence
of the screen proc implies zero aux planes for all
of the screen's supported modifiers.  Hence, when
a driver does not expose the proc, derive the
number of planes directly from the format.

6ec7e0d406 gallium: document convention for get_handle calls on multi-planar resources
There are resources that may have more planes than chained resources. The
frontend has no way of figuring out which (if any) chained resource is the
right one to call resource_get_handle with and until a (now reverted)
change to the dri frontend it just always called with the first resource.

The convention of calling with the first resource of a chain allows the
pipe driver, which has the necessary information of how resources and
planes map to each other for a specific format/modifier combination, to do
the necessary walking. Document this as the official calling convention
of this function.
