James Jones 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.
