refactor(ck): mx gemm kernel unification

## Motivation

CK tile currently has two separate MX GEMM kernels for gfx950 and
gfx1250. This pull request refactors and modernizes the MX GEMM kernel
and example to use new scale tensor handling, improved kernel argument
structures, and updated pipeline and kernel APIs. The changes simplify
the interface and improve type safety.

JIRA ID ROCM-26313

## Technical Details

- Add support for gfx950 in MX GEMM kernel for gfx1250 and remove unused
kernel
 - Unify comp async pipeline for GEMM and MX GEMM
 - Unify eight waves pipeline for GEMM and MX GEMM
 - Move preshuffle MX GEMM pipeline to gemm ops and remove gemm_mx ops
 - Unify testing framework for MX GEMM
 - Add gfx950 tests for grouped MX GEMM

## Test Plan

 - `test_mx_gemm_async.cpp` for MX GEMM on gfx950
 - `test_mx_grouped_gemm_comp_async.cpp` for grouped MX GEMM on gfx950

CK Tile Testing Guide

This document describes the test organization and available test targets for CK Tile operations.

Overview

CK Tile tests are organized with multiple levels of granularity to support different development workflows:

  1. Global test labels - Run tests across all operations
  2. Operation-specific umbrella targets - Run all tests for a specific operation
  3. Individual test executables - Run specific tests

Global Test Labels

These targets run tests across all CK operations (not just CK Tile):

ninja smoke

Run fast smoke tests (tests that complete within ~30 seconds on gfx90a).

ninja smoke

ninja regression

Run slower, more comprehensive regression tests.

ninja regression

ninja check

Run ALL available tests in the entire codebase.

ninja check

Operation-Specific Umbrella Targets

These targets allow you to run all tests for a specific CK Tile operation. This is useful when making changes to a particular operation and wanting to validate all related tests without running the entire test suite.

GEMM Operations

ck_tile_gemm_tests

Run all basic GEMM pipeline tests (memory, compute variants, persistent, etc.)

ninja ck_tile_gemm_tests

Test executables included:

  • test_ck_tile_gemm_pipeline_mem
  • test_ck_tile_gemm_pipeline_compv3
  • test_ck_tile_gemm_pipeline_compv4
  • test_ck_tile_gemm_pipeline_persistent
  • test_ck_tile_gemm_pipeline_compv6
  • test_ck_tile_gemm_pipeline_comp_async (gfx95 only)
  • test_ck_tile_gemm_pipeline_*_wmma variants (gfx11/gfx12 only)

ck_tile_gemm_block_scale_tests

Run all GEMM tests with block-scale quantization (AQuant, BQuant, ABQuant, etc.)

ninja ck_tile_gemm_block_scale_tests

Test executables included: 29 test executables covering:

  • AQuant tests (memory pipelines, base layouts, prefill, preshuffle, transpose)
  • ABQuant tests (base, padding, preshuffle)
  • BQuant tests (1D/2D variants, transpose)
  • BQuant with PreshuffleB (decode/prefill, 1D/2D)
  • BQuant with PreshuffleQuant (decode/prefill, 1D/2D)

  • test_ck_tile_grouped_gemm_quant_bquant_preshuffleb

Other Operations

ck_tile_fmha_tests

Run all FMHA (Flash Multi-Head Attention) tests

ninja ck_tile_fmha_tests

Test executables included: Forward and backward tests for fp16, bf16, fp8bf16, fp32

Individual Test Executables

You can also build and run individual test executables:

Build a specific test

ninja test_ck_tile_gemm_pipeline_mem

Run a specific test directly

./build/bin/test_ck_tile_gemm_pipeline_mem

Run a specific test through ctest

ctest -R test_ck_tile_gemm_pipeline_mem --output-on-failure
