replace vendor specific sort calls with kokkos::sort using custom comparator

[cwsmith]

Kokkos 4.2.0 kokkos/kokkos#6197 is adding 'sort: support custom comparator kokkos/kokkos#6253'. We should try to replace the Intel DPL and HIP/CUDA Thrust sorting calls with this:

omega_h/src/Omega_h_sort.cpp

Lines 51 to 60 in 08e643b

	#if defined(OMEGA_H_USE_KOKKOS) and defined(OMEGA_H_USE_SYCL)
	auto space = Kokkos::Experimental::SYCL();
	const auto q = *space.impl_internal_space_instance()->m_queue;
	auto policy = ::oneapi::dpl::execution::make_device_policy(q);
	oneapi::dpl::sort(policy,b,e,c);
	#elif defined(OMEGA_H_USE_CUDA) || defined(OMEGA_H_USE_HIP)
	auto bptr = thrust::device_ptr<T>(b);
	auto eptr = thrust::device_ptr<T>(e);
	thrust::stable_sort(bptr, eptr, c);
	#elif defined(OMEGA_H_USE_OPENMP)
