ea436ef09d windows: add iphlpapi routing functions 
NotifyRouteChange2 registers to be notified for changes to IP route
entries. Call GetIpForwardEntry2 on received row to retrieve complete
information.

GetIpForwardTable2 retrieves the full routing table.
FreeMibTable frees the buffer allocated by the functions that return
tables of network interfaces, addresses, and routes.

7143f4a4e1 windows: manually initialize NewNTUnicodeString

The process is described in [WdmlibRtlInitUnicodeStringEx](https://learn.microsoft.com/en-us/windows-hardware/drivers/ddi/wdmsec/nf-wdmsec-wdmlibrtlinitunicodestringex).

The less syscalls, the better. It also makes the function faster:

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.

1a50d9738b windows: add serial comm functions 
Serial ports are still widely used to communicate with a large range of
devices.

This change adds the remaining functions described in "Serial
Communications in Win32", enabling Go applications and libraries to be
written that support the full set of serial port functionality on
Windows.

x/sys/unix already has equivalent functionality through termios.

See https://learn.microsoft.com/en-us/previous-versions/ms810467(v=msdn.10).

c8ea6b0cbc windows: fix EnumProcesses to pass the correct array size 
Implementation generated directly with mkwinsyscall has a wrong
assumption about the expected value for PIDs buffer size.

This change adds some small manual code that converts the input
slice length to the number of bytes of the array backing the slice.

A test is also added. It fails with the previous implementation.

Fixes golang/go#60223

a6f4650873 windows: use UTF16FromString and UTF16ToString from syscall 
This CL updates the windows.UTF16FromString and windows.UTF16ToString
implementation so they forward to their syscall counterparts.

The standard library uses these particular syscall functions across
the board as it can't depend on x/sys. This means that even if the
syscall API is frozen, the implementation still receives improvements
and bug fixes, such as CL 425054.

Porting CL 425054 to x/sys is possible, but for this particular case
I think it's better to just call the syscall package. This way both
repos will benefit from future improvements (which I plan to do soon).

fe61309f88 windows: add SetupAPI and CfgMgr32 functions 
Simon and I have worked on these on and off for a number of projects
over the last 3 years and by now it's quite stable and mature. Rather
than carrying this around privately, these have now been updated to be
in the style of x/sys/windows, in this case matching how the
security_windows.go file does things. Specifically, because these APIs
are kind of hard to work with, and quite lengthy, we split them off into
a setupapi_windows.go file, just like security_windows.go.  We already
had the setupapierrors_windows.go file, so that's been folded into the
new one that contains the additional definitions nad functions.

These APIs are among the most obtuse to work with in all of Win32, so
considerable attention has been spent trying to make these wrappers both
quite "raw" so that they match the win32, but also accessible from Go.
The fact that they're so old in Windows history makes for a few tricky
things, like struct padding that doesn't quite match Go's rules, but
we've been able to accommodate basically everything after quite a bit of
work.
