  [libc++] Check _LIBCPP_USE_CLOCK_GETTIME before using clock_gettime

The clock_gettime function is available when _POSIX_TIMERS is defined.
We check for this and set _LIBCPP_USE_CLOCK_GETTIME accordingly since
59b3102739c. But check for _LIBCPP_USE_CLOCK_GETTIME was removed in
babd3aefc91. As a result, code is now trying to use clock_gettime even
on platforms where it is not available and it is causing build failure
with newlib.

This patch restores the checks to fix this.

  [libcxx] Avoid overflows in the windows __libcpp_steady_clock_now()

As freq.QuadValue can be in the range of 10000000 to 19200000,
the multiplication before division makes the calculation overflow
and wrap to negative values every 16-30 minutes.

Instead count the whole seconds separately before adding the
scaled fractional seconds.

Add a testcase for steady_clock to check that the values returned for
now() compare as bigger than the zero time origin; this
corresponds to a testcase in Qt [1] [2] (that failed spuriously
due to this).
