…ses a combination of Iscas in-built macros with overload_c4 etc, whilst maintaining other default flags.
…ountered with the simple cloud fortran files, which had missed a few file-exists imports from fms-mod. Also lcl.f90 explicitly defined variables as double precision, which caused problems when variables were inputted to its functions as single. Now changed to real so that compiler chooses the representation of real.
… precision, but should not be there for single precision. Do not currently have a dynamic way of editing that mkmf template file, so added feature to choose different mkmf template file for single precision. Format is just same name as current mkmf template file with _simple added at the end.

We want to be able to run Isca using single-precision arithmetic, rather than the default double precision. This p/r mirrors some code I wrote way back in 2020:
sit23@efd0195
This change gives a method on the codebase object to allow the compile flags to be set to do single precision arithmetic, rather then double, but leaves double as the default.
I've added a new held-suarez test case to show how this method is to be used.
N.B. this only works at the moment for Intel compilation.
