QTimerInfo: store nanoseconds instead of milliseconds
No change in behavior, other than the ability for the precise timers to
be even more precise. There's a reduction in the stored interval range
from 292 million years to 292 years, but there's no change in behavior
because the timeout is stored as a steady_clock::time_point, which is
nanoseconds with libstdc++ and libc++. Now, if there's an overflow,
it'll happen on the call to registerTimer() instead of inside the
calculation of the wake-up.
