unix: add missing ETHTOOL_FLAG_ constants

Some constants were removed in CL 600516 that included changes for the
Linux kernel 6.10.

This kernel version moved C defines to an enum ethtool_header_flags that
was not picked up by the mkall.sh script.

For enums, there is a perl script that needs to be run manually, and the
output must be added by hand to the list of constants in unix/linux/types.go.

See https://elixir.bootlin.com/linux/v6.10.3/source/include/uapi/linux/ethtool_netlink.h#L120

Fixes golang/go#68761

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

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.

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.
