While the types_windows file previously had a small handful of types,
this forced application code to have an awkward mixture of artisanal
error constants and factory-ready ones. This commit adds the missing
ones and separates them into a new file, since they are quite numerous.
These also preserve the order of winerr.h, which should make it somewhat
easier to import new ones in the future.

We already have all the structs and constants for async I/O, and the
various functions of x/sys/windows take the right parameters. But we're
missing the final step of any ordinary async I/O routine: getting the
result of overlapped I/O. Without this, the rest of the plumbing
supported by this module isn't actually so useful. So add this small
oversight.

The previous selection was a bit haphazard, and defining random
constants in an application and combining those with existing constants
in this library looks kind of weird. So instead let's add the actual set
of flags, instead of the strange prior assortment.
