[CK_TILE] Support multi-config in tile_example_gemm_universal (#2240)

* [CK_TILE] Support multi-config in tile_example_gemm_universal

Add GemmConfig in run_gemm_example to support multiple tile config.
- It is useful when use you need compare gemm perf with different tile/pipeline config
- we also can use it simplify the code for wmma support in the furture.

* [CK_TILE] Support multi-config in tile_example_gemm_universal

Address review comments

* rebase code and fix clang format.

* fix clang format

* support pipeline v5.

* fix merge conflict

* address review comment

* add missing file

* address review comment v2

* fix build error
