  Changed paths:
    M libcxx/include/__math/abs.h
    M libcxx/include/math.h
    M libcxx/include/stdlib.h
    M libcxx/test/std/numerics/c.math/abs.verify.cpp

  Log Message:
  -----------
  [libc++] Move std::abs into __math/abs.h (#139586)

`template <class = int>` is also added to our implementations to avoid
an ambiguity between the libc's version and our version when both are
visible.

This avoids including `<stdlib.h>` in `<math.h>`.
