Default constructor.

RocfftInitializer gmx::Gpu3dFft::ImplSyclRocfft::Impl::init_

Handle initializing the rocFFT library.

Make sure the library is initialized before the plans, etc. and not destructed before they are.

sycl::queue gmx::Gpu3dFft::ImplSyclRocfft::Impl::queue_

Copy of PME stream.

This copy is guaranteed by the SYCL standard to work as if it was the original.
