173 implement device grouped gemm fixed nk for rdna4

## Proposed changes

This PR adds an RDNA4 implementation of the device_grouped_gemm_fixed_nk
instance library using for WMMA.

The implementation is based on the existing
DeviceGroupedGemm_Xdl_Fixed_NK design and reuses the same high-level
structure, but replaces the XDL kernel with a WMMA-based one. It uses
the GridwiseGemm_wmma_cshuffle_v3 kernel.

At this stage, the focus is functional correctness and compatibility,
not performance tuning.

## Technical Details

- Device struct for grouped gemm fixed NK
- Example code for the WMMA version
- Unit tests for both new wmma implementation and the reference XDL code
(previously missing)
- Generic ck profiler interface with the purpose of calling unit tests.
