Extend getrs with trans_code argument

[vlad-perevezentsev]

This PR suggests expanding getrs function by adding trans_code argument and handling its values to match the behavior of oneapi::mkl::lapack::getrs

These changes are the first step to implement lu_solve(lu_and_piv, b, trans=0, overwrite_b=False, check_finite=True)
