CLM Lake restarts nine 3D fields that are constant

[SamuelTrahanNOAA]

Description

These fields in the CLM Lake model are constant:

• lake_z3d
• lake_dz3d
• lake_soil_watsat3d
• lake_csol3d
• lake_soil_tkmg3d
• lake_soil_tkdry3d
• lake_soil_tksatu3d
• lake_clay3d
• lake_sand3d

The later seven are 2D arrays that are needlessly duplicated in the vertical (lake k) dimension. The first two are 3D. All of these are sparse arrays, zero everywhere except lake points.

All nine should be removed.

Steps to Reproduce

1. Read the code. The lakeini in clm_lake.f90 calculates those variables. They're never modified after that.

Additional Context

The CLM Lake Model is taking up too much disk space in the RRFS. Removing these nine variables would reduce that problem.
