Configure single_propmat_agenda for Earth microwave gas refraction.

The agenda initializes all single-frequency propagation quantities and adds the Earth microwave gas refractivity. Pair it with ray_point_back_propagation_agendaSet(option="RefractiveStepwise") and a frequency-dependent propagation method such as spectral_radClearskyEmissionFrequencyDependentPropagation().

The resulting agenda contains no absorption model. Build a custom single_propmat_agenda when absorption and refraction are both needed.
