f34bb9fccc windows: add net user enum 
In the go windows package, you can get user information by using
`NetUserGetInfo` along with a specified level. However, there is
no way to get a list of the users.
The only options are to
1. know the users,
2. brute force users, or
3. use an external tool or command (`net users`).

I suggest adding a function that implements the windows api for
`NetUserEnum`. This will allow a built in way to enumerate
users and follow the standard.

A side note is that I used `buf **byte` because
it is how the others are done, but using `buf *byte`
works just as well.

7d69d983c4 unix: extend support for z/OS 
This change syncs the IBM internal version of sys/unix with the public
repository.

There are a variety of new syscalls and const definitions that have been
accumulated over the past few years to support developers using Go on
the platform. Old simulations of calls like 'epoll' and 'fstatfs' have
been replaced with their real counterparts. The zos/s390x syscalls also
have extensive trampolining to handle zos systems that might not have
support for some of these new system calls.

Closes golang/go#67071

cabba82f75 windows: use uint32 for serial comm flags for consistency 
This is a follow-up to https://go-review.googlesource.com/c/sys/+/572295
and specifically the comment
https://go-review.googlesource.com/c/sys/+/572295/comment/a00e1a2e_e3b01666/.

All other structs and methods us uint32 in golang.org/x/sys/windows
for flag bitmasks, so make the serial communication structs use uint32
to be consistent with the rest of the package.

As a side effect the DTR_CONTROL_* and RTS_CONTROL_* constants are
updated to reflect the positions of the bits in the 32-bit flags.

914b96c1bd windows: support ill-formed UTF-16 in UTF16PtrToString 
UTF16PtrToString does not support ill-formed UTF-16 because it uses
utf16.Decode, which expects well-formed UTF-16.

This CL updates the UTF16PtrToString implementation to use
UTF16ToString instead of utf16.Decode, which supports ill-formed
UTF-16 since go1.21 via syscall.UTF16ToString.
