[CK Tile] Eight Waves pipeline for MX GEMM (#5552) ## Motivation Integrate Eight Waves pipeline in MX GEMM ## Technical Details - EightWaves pipeline: - Add pipeline, policy and block gemm (internally using existing implementation used by GEMM and ABQuant) - Extend support of EightWaves policy for FP4 (packed types) - Async pipeline: - Fix pipeline with packed scales (requires MRepeat and NRepeat to be contiguous) - block gemm specific for MX GEMM is defined because distribution encodings have changed - CShuffle: - Add new functionality to support MRepeat and NRepeat contiguous (defined by `TilesPacked`) - Examples: - Refactor examples to easily switch different configurations (similar to GEMM universal) - Scales values generated consistently with other microscale implementations in CK Tile - Add configuration for EightWaves pipeline - Tests: - Unify existing FP8 and FP4 tests - Add tests for EightWaves pipeline - Scales values generated consistently with other microscale implementations in CK Tile Note: FP6 support for MX GEMM was added later and the support for the Eight Waves pipeline will be done in following PR ## Test Plan Add new pipeline to tests: `test_ck_tile_mx_gemm_async` for both FP4 and FP8 ## Submission Checklist - [x] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests.
