Ck tile GPU verification sample develop & Add the CK TILE GEMM to the CI/CD test (#1505)

Browse Source 
* Finished the feature of gpu verification

* Add the ck_tile_gemm test in the CI CD

* add the include of tensor_layou in reference_gemm

* Comment Addressed

* split ck_tile fhma and gemm tests into separate stages

* restructure the reference gemm

* restructure a new reference_gemm api that could read the device mem
