[OneMKL] [BLAS] data type of transa and transb in gemm and gemv

[vtavana]

Should oneapi::mkl::transpose be used instead of onemkl::transpose as the data type of transa and transb in gemm, gemm_batch, gemv, and gemv_batch? If yes, the change should be applied to all variants of each function.

For instance, here

@vtavana Yes thanks for pointing is out. The namespaces needs to be updated in all relevant APIs.
