intel/blorp: Support some image/buffer blit operations using compute

Reworks:
 * Use BLORP_BATCH_USE_COMPUTE flag rather than compute param to
   blorp_copy (s-b Jason)
 * Squash "intel/blorp: Set shader_pipeline for compute"
 * Squash "intel/blorp: Add blorp_copy_supports_compute function"
 * Squash "intel: Support compute for image/buffer copy if INTEL_DEBUG=blocs
           is set"
 * Squash "intel/blorp: Support compute for some blit operations"
 * Use nir_image_store (s-b Jason)
 * Use nir_push_if (s-b Jason)
 * Require gfx12 for ccs in blorp_copy_supports_compute (s-b Jason)
 * Add nir_pop_if (s-b Ken)
 * Fix aux_usage check on gfx12 blorp_copy_supports_compute (s-b Ken)
 * Use blorp_set_cs_dims (s-b Jason)
 * Use dim=2d with array=true for nir_image_store (s-b Jason, Francisco)
 * Restructure gen checks in blorp_copy_supports_compute (s-b Ken)
 * Use nir_load_global_invocation_id (s-b Jason)
 * Fix inefficient calculation of store_pos (s-b Jason)
 * Use bounds_if being NULL/non-NULL for nir_pop_if (s-b Jason)
 * discard => bounds (s-b Ken)
 * Re-add ISL_AUX_USAGE_CCS_E in *_supports_compute (s-b Sagar)
 * Skip duplicated in_bounds calculation (s-b Jason)
