This is a refactor that moves overflow verification functions from
pandas/_libs/src/vendored/numpy/datetime/np_datetime.ctopandas/_libs/include/pandas/portable.h, and uses Generics to handle multiple integer types on Windows.This was originally from #62741, but this change a little bit unrelated to the fix, but I need the functions from this refactor to perform the overflow verifications.
