Support for dtypes (fp8, bf8, bf16 and fp16) for the ck_tile/03_gemm example. (#1845)

* Support bf16/fb8/bf8 datatypes for ck_tile/gemm

* remove commented out code.

* Addressing code review comments and enabling universal_gemm for all the supported data types.

* Merge conflict resolution.

* Solve the memory pipeline compilation error. Merge with the new change of CShuffle

* finish the feature, pass the tests

* Fix the pipeline and add the benchmark script for other data types
