Uninitialized Grid variables in GFS_typedefs.F90 grid_create

[SamuelTrahanNOAA]

Description

Several of the Grid% variables are allocated but not initialized in grid_create in the GFS_typedefs.F90

To Reproduce:

What compilers/machines are you seeing this with?

All.

This was discovered while debugging these problems. I used valgrind on a RRFS gnu regression test with 32-bit physics:

• 32-bit physics crashes in aerinterp due to type mismatch in NetCDF calls. ufs-community/ccpp-physics#83
• aerinterp routines do not pass NetCDF errors up through errmsg and errflg ufs-community/ccpp-physics#84

Additional context

N/A

Output

N/A

Testing:

Tested on hera. There are new regression tests for RRFS with 32-bit physics.
