e8f71f6ac4 mesa/st: add PIPE_CAP_GL_CLAMP 
when this is not set, this triggers shader and sampler state updates any time a sampler
starts or stops using GL_CLAMP, applying bitmasks needed to run nir_lower_tex
and setting CLAMP_TO_BORDER/CLAMP_TO_EDGE as necessary to mimic the behavior

175c827e72 gallium: Flip the default value of PIPE_CAP_SHAREABLE_SHADERS. 
We should be exposing it in every driver, since it's required eventually
to reduce jank.  Make drivers have to explicitly opt out instead of opt
in.

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.

6ee10ab3de gallium: Add pipe_screen::is_dmabuf_modifier_supported 
Add a "do you support this modifier?" query to all
drivers which support format modifiers. This will
be used in a subsequent change to fully
encapsulate modifier validation and auxiliary plane
count calculation logic behind the driver
abstraction, which will in turn simplify the
addition of device-class-specific format modifiers
in the nouveau driver.
