This is EMC flake model

[YihuaWu-NOAA]

Modify files in ufs-weather-model-flake/FV3/gfsphysics/GFS_layer/
GFS_typedefs.F90
GFS_typedefs.meta
Note: Added two variables: lakedepth and LKM (logical)

Modify file in ufs-weather-model-flake/FV3/io/
FV3GFS_io.F90
Note: read in lake depth, and reset lakefraction and lakedepth to 0 when LKM is not one

Modify files in ufs-weather-model-flake/FV3/ccpp/physics/physics/

Added threes:
flake_driv.F90
flake_driv.meta
flake.F90*

Modified:
GFS_time_vary_pre.fv3.F90
Note: Flake need julian day

3.3 Modified:
GFS_surface_composites.F90
GFS_surface_composites.meta
Note: add lake depth, and define the logical variable lake based on lakefraction and lakedepth
Then, the logical variable lake is passed to flake drive and sfc_ocean.
When lake is true, flake will be called; when lake is false, ocean model will be called

3.4 Modified
sfc_ocean.F
sfc_ocean.meta
Note: add lake, if not lake, calculation will be conducted.

Modify files in mylakedir/sorc/orog.fd
lakefrac.F90 to create lake fraction and depth and add them to oro_data_tilex.nc

Replace oro_data_tilex.nc files on hera: /scratch2/NCEPDEV/fv3-cam/Yihua.Wu/noscrub/trunk-20200611 which provide model inputs.
A new baseline was created on hera: /scratch2/NCEPDEV/fv3-cam/Yihua.Wu/noscrub/REGRESSION_TEST_INTEL

This PR is for NCAR dtc/develop. You are having at least one other, identical PR for ufs-community develop (where it should be). I am thus closing this PR.
