Added tests for error macros on GPU.

Some simple tests for the new error macros defined in the opm-common PR 4465.

I think something has gone wrong with the macro that assess whether we are inside a GPU kernel or not, as I get an error on an AMD gpu as it expands the wrong macro from ErrorMacros.h. It should have expanded the macro on line 110 in ErrorMacros.hpp

minimal example that can not be compiled on HIP

#include <hip/hip_runtime.h>
#include

global void test_kernel() {
#if defined(CUDA_ARCH) || (defined(HIP_DEVICE_COMPILE) && HIP_DEVICE_COMPILE > 0)
printf("Hello from HIP kernel!\n");
#else
static_assert(false, "This should not be compiled for host");
#endif
}

int main(int, char**) {
test_kernel<<<1, 1>>>();
hipDeviceSynchronize();
return 0;
}

I think this should now compile on HIPCC, @multitalentloes
