[CK] Remove code duplications in grouped gemm fixed nk implementations (#4961) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Motivation Different flavours of grouped gemm fixed nk implemenations share the same block to tile mapping logic. Despite that the code responsible for it is duplicated in each device struct implementation. - Move `BlockToCTileMap_KBatch_M00_N0_M01Adapt_MLoops` and `OffsettedBlockToCTileMapMLoops` from the device struct implementations to a common header file. - Use the generic Kernel Argument structures in xdl versions of the fixed nk. ## Technical Details <!-- Explain the changes along with any relevant GitHub links. --> ## Test Plan CI in general. Relevant test and examples are all fixed_nk versions of grouped gemm multiple D and ABD. ## Test Result <!-- Briefly summarize test outcomes. --> ## Submission Checklist - [ ] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests.
