[wpiutil] Unbreak wpi::Format on Windows (#3242)

This function relies on the behavior of snprintf returning an error value
when the buffer is too small.  By default, _snprintf_s aborts on Windows
instead of returning an error value.

This caused Glass to fail when trying to print a large NT value to a string.
