Make surface emissivity over water a persistent variable #434

Description

The surface emissivity over water is currently stored in the GFS_interstitial_type DDT, which is not persistent. To fix the issues described in ufs-community/ufs-weather-model#914, it needs to be moved to a persistent data type. This PR moves it to the GFS_sfcprop_type, which is already home to the surface emissivity over land and ice.

Note that in the long run, in case restart reproducibility is broken, Sfcprop%emis_wat might need to be added to the restart files. Right now it doesn't matter, because the emissivity over water is just a constant value that gets set again and again each time step.

Adding @SMoorthi-emc only for his information later on, because he is on leave for the rest of the year.
