[CK Tile] Add gemm universal preshuffle to MX GEMM (#5647)
## Motivation
Add gemm universal preshuffle support to existing MX GEMM pipeline.
The straightforward way to do this is to port the `mx_flatmm` pipeline
to the existing `gemm_mx` framework.
## Technical Details
The `mx_flatmm` pipeline was not deleted, to allow for
back-compatibility.
## Test Plan
Add `preshuffle` option to example: `tile_example_mx_gemm`.
Add new configurations with enabled preshuffle to the existing
`test/ck_tile/gemm_mx` tests.
## Test Result
Example and tests were successful on `gf950` architecture in the `Alola`
cluster.

[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
