Enable oneMath support for dpnp builds (#2313)

Since `oneMKL Interfaces` has been renamed to `oneMath` this PR suggests
adding automatic interface name detection for future releases while
maintaining compatibility with the old unrenamed versions (onemkl)

Additionally changes `oneMKL` repository URL to `oneMath`
