This is an attempt to remove the magic from a lot of the numbers tested, which should make things easier when it is time to add `f16` and `f128`. A nice side effect is that these tests now cover all int <-> float conversions with the same amount of tests.

Thanks! Is it possible to make this a PR in the Miri repo? We have more test coverage there (such as a big-endian target). |

f16andf128in this PR since we still dont have the constants needed for many of these tests (they will come in #126608, but that is blocked on #126636 and possibly #125016).r? @RalfJung
