FortranCInterface: Fix compatibility with GCC gfortran 12 LTO
Since version 12.0 the GCC Fortran compiler has implemented "WG5/N1942",
which causes, if link-time opmization is enabled, obfuscation of hard-coded
string values in the compiler objects and its resulting ELF-binaries.
This causes the CMake-internal detection of the mangling scheme for the
naming of subroutines to fail. Thus we must ensure to have any link-time
optimization features to be disabled on the executable file we perform the
detection on.
The static libraries, however, must be build with LTO and non-LTO objects,
as that will ensure the verify step will operate on IPO objects, if building
those is requested by the system compiler flags.
Fixes: #23123
