WinCE: Fix race between wince_clock_gettime_threaded() and wince_clock_gettime()
* When the timer thread is created in wince_init(), it performs an initialisation
phase in which it uses QueryPerformanceFrequency() to determine if there is a
high resolution timer available, and sets hires_frequency and hires_ticks_to_ps
appropriately. However, since wince_init() does not wait for this initialisation
phase to complete, wince_clock_gettime() can be called before hires_frequency
and hires_ticks_to_ps have been updated. This can result in
wince_clock_gettime() temporarily returning real-time clock values even though
the platform supports a monotonic clock.
