[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.
