  -----------
  [libc][math][c23] Add fmodl and fmodf128 math functions. (#84600)

- Allow `FMod` template to have different computational types and make
it work for 80-bit long double.
- Switch to use `uint64_t` as the intermediate computational types for
`float`, significantly reduce the latency of `fmodf` when the exponent
difference is large.
