[Windows] Can't set high process I/O priority + provide IO constants #1476

It only accepts 0, 1 and 2 as valid values, meaning very low, low and normal priority respectively, but we also have 4 (high) which currently cannot be set (raises ValueError). Also, it makes sense to expose these 4 numbers as module constants so that we won't have to pass plain integers.
