NVHPC (nvfortran) compiler fails during make with `TERMINATED by signal 11`

When building SELF using the nvhpc compilers (v24.5), the compiler terminates while compiling `src/SELF_MappedScalar_2D_t.f90` with `TERMINATED by signal 11`; all other compilers are able to compile without any issue. Until this is resolved, we will be disabling the tests with nvfortran build. We will attempt to reach out to Nvidia about this one.

This issue can be found in our github actions ( https://github.com/FluidNumerics/SELF/actions/runs/10853816248/job/30122907452?pr=53 ) and is able to reproduced on Oram at the Fluid Numerics shop.
