Test: cgal/cgal_mesh_criteria: disable floating point exceptions

Test: cgal/cgal_mesh_criteria: disable floating point exceptions

We trigger a (deliberate) floating point exception in the CGAL (header)
library:
```
    // The multiplications could produce some NaN, with 0 * inf. Replacing it with inf is safe.
    // min(x,y) (the order is essential) returns its second argument when the first is NaN.
    // An IEEE 754-2019 maximum could help.
    __m128d big = IA::largest().simd();
->  __m128d x1 = _mm_mul_pd(aa,bz);                       // {-ai*bi,as*bs}
    //x1 = _mm_min_pd(x1,big); // no NaN
    __m128d x2 = _mm_mul_pd(aa,c);                        // {-ai*bs,as*bi}
    x2 = _mm_min_pd(x2,big); // no NaN
    __m128d x3 = _mm_mul_pd(ap,bz);                       // {-as*bi,ai*bs}
    //x3 = _mm_min_pd(x3,big); // no NaN
    __m128d x4 = _mm_mul_pd(ap,c);                        // {-as*bs,ai*bi}
    x4 = _mm_min_pd(x4,big); // no NaN
```

Thus, disable floating point exceptions for the test.
