[win32] optimized calibration cycle (makes Tcl for windows "RTS" resp. NRT-capable):
- the clock ticks never backwards (avoid it by negative drifts using comparison of times before and after calibration);
- more precise, smooth/soft drifting (avoids too large drifts, already after 10 iterations the drift gets fewer as 0.1 microseconds);
- because of more accurate drifting (aspire to the smallest difference), we can prolong calibration interval (up to 10 seconds by small tdiff-value);
Closes ticket [b7b707a310ea42e9f1b29954ee8ca13ae91ccabe] "[win32] NRT-only - NativeGetTime backwards time-drifts bug"
