gh-112567: Add _PyTimeFraction C API (#112568)
Use a fraction internally in the _PyTime API to reduce the risk of
integer overflow: simplify the fraction using Greatest Common
Divisor (GCD). The fraction API is used by time functions:
perf_counter(), monotonic() and process_time().

For example, QueryPerformanceFrequency() usually returns 10 MHz on
Windows 10 and newer. The fraction SEC_TO_NS / frequency =
1_000_000_000 / 10_000_000 can be simplified to 100 / 1.

* Add _PyTimeFraction type.
* Add functions:

  * _PyTimeFraction_Set()
  * _PyTimeFraction_Mul()
  * _PyTimeFraction_Resolution()

* No longer check "numer * denom <= _PyTime_MAX" in
  _PyTimeFraction_Set(). _PyTimeFraction_Mul() uses _PyTime_Mul()
  which handles integer overflow.
