This PR resolves #96322 and implements the `signbit` macro under a new header `generic-math-macros.h`. This also removed the `TODO` in `math-macros.h` and moves `isfinite`, `isinf`, and `isnan` to the same generic maths header. Finally, a test file `generic-math-macros_test.cpp` that adds coverage to the above 4 macros. Fixes #96322.
