Checks placed before allocating pointers passed into routines

[ganganoaa]

Description
Checks are inserted mostly for member pointers of DDTs, which are passed as arguments to functions and subroutines, before allocation.

Fixes #1099

How Has This Been Tested?
The update was tested with 'make check' and 'make distcheck' without any issues on OS, 'CentOS Stream 8'. The following setup was used for compiler, MPI wrapper, and required packages:
oneapi v2022.2
hdf5 v1.12.0
tbb v2021.6.0
oclfpga v2022.1.0
netcdf v4.9.0
mpich v4.0.3
compiler-rt v2022.1.0
compiler v2022.1.0

We may have discussed this but I forget. Why are these pointers not changed to allocatables?

[ganganoaa]

There are many functions and subroutines that have pointer return types and arguments.
