POD version of TPCFastSpaceChargeCorrection

[shahor02]

Created from the TPCFastTransform using:

std::vector<char> buff; // can be also pmr::vector from DPL make(..) const o2::gpu::TPCFastTransformPOD& pod = o2::gpu::TPCFastTransformPOD::create(buff, tpc_fast_transform);

The buff vector will be expanded during creation and can be sent over DPL. On the receiving side, it should be cast as:

const auto& podTransform = o2::gpu::TPCFastTransformPOD::get(pc.inputs().get<gsl::span<char>>(ref));

No initialization is needed, the transform methods (at the moment all methods of TPCFastSpaceChargeCorrection are implemented) can be directly queried from the object received over sh.memory.
