Rework handling of evaporation constraint in SoilFluxes

Occasionally, h2osoi_ice was going significantly negative in
UpdateState_TopLayerFluxes - see
ESCOMP#1979. As noted in that issue, this
seems to be due to h2osoi_ice having a very different magnitude from
h2osoi_liq, leading to greater-than-roundoff-level differences from zero
final state in a relative sense (i.e., relative to the magnitude of
h2osoi_ice) - I think because of the appearance of the sum (h2osoi_ice +
h2osoi_liq) in the equations that limit fluxes.

To try to deal with this, I have reworked the handling of the
evaporation constraint to directly limit both the liqevap and solidevap,
so that both of them should result in the equivalent liq or ice states
going to 0 within roundoff.

To do that, I needed to move the partitioning of the total flux into
liquid and solid to earlier in the subroutine and then recalculate those
partitioning fluxes in conditions where we're applying an evaporation
constraint.

Note that I applied a max of 0 to the new fluxes because many initial
conditions files have roundoff-level negative H2OSOI_LIQ, so without
this limit, we were getting roundoff-level negative fluxes.
