[BLAS][HIP] Fix blas support for rocBLAS 4+

[npmiller]

Description

Patch is similar to https://github.com/oneapi-src/oneMKL/pull/448 (thanks @nilsfriess ) but with only the ifdef part to make the rocBLAS 4 build work.

I've tested with ROCm 5.4.3 (rocBLAS 2), and ROCm 6.1.0 (rocBLAS 4), I've also tested the build with ROCm 5.7.1 (rocBLAS 3), the new interface seemed to cause build issues with rocBLAS 3 so I kept the legacy one.

Information on the deprecated interface here.
