Updates to SGS cloud interstitials, adding C-B cloud fraction for convection schemes

[joeolson42]

Description: Enhancement - This modification adds:

1. A new cloud fraction (Chaboureau and Bechtold 2005) for the GF convection scheme.
2. The capability to separate frozen subgrid clouds into both snow and ice (no longer just ice).
3. Had to switch array "ud_mf" from interstitial to TBD block and add it to the restart files.

Issue(s) addressed

The modifications in this PR improve the radiation balance in the tropics by providing a cloud fraction diagnostic that seems to be more compatible with the GF convective scheme.
