Followup of #13242: This optimizes the IOContext#withReadAdvice() method to use precalculated instances of IOContext to not create new instances all the time.

I think last one is shortest. EnumMap would have been fine, but as it is all an internal cache, a simple array on enum's ordinal number is enough (same approach like switch statements on enums use).
