[3.12] gh-102837: more tests for the math module (GH-111930)(GH-102523) (GH-112030)

* gh-102837: improve test coverage for math module (GH-102523)

(Only the test changes from GH-102523 are cherry-picked)

- input checks for math_1(L989), math_1a(L1023), math_2(L1064,L1071), hypot(L2682), log(L2307), ldexp(L2168), ceil(L1165), floor(L1236,L1239) and dist(L2587,L2588,L2628).
- improve fsum coverage for exceptional cases (L1433,L1438,L1451,L1497), ditto fmod(L2378)

(all line numbers are wrt the main branch at 5e6661bce9)
