[NDSL] UW convection port

[FlorianDeconinck]

Located at GEOS_UW_InterfaceMod.F90:UW_Run, main subroutine "compute_uwshcu_inv" but everything Run should be ported

Parent: GEOS-ESM/SMT-Nebulae#57

In the conden function locals are R8/F64 variable, e.g.

      ! Local
      real*8               :: tc
      real                 :: temps,ps
      real*8               :: leff,nu,qc
      integer              :: iteration
      real*8               :: qs    ! Saturation specific humidity

This is true mixed precision computation, which we can't do in stencils for now.
