Replace syscall.Syscall6, Syscall9, Syscall12, and Syscall15 with
syscall.SyscallN for Go 1.18+. This simplifies system calls by allowing
the exact number of arguments needed, eliminating zero padding and
reducing potential errors.

Updated TestSyscallXGeneration to TestSyscallNGeneration to verify
correct SyscallN generation for different argument counts.

6a85559a3f windows: fix dangling pointers in (*SECURITY_DESCRIPTOR).ToAbsolute 
Prior to this CL, a byte slice was allocated via make to use as the
absoluteSD argument passed to the Windows API MakeAbsoluteSD.

MakeAbsoluteSD then sets pointers outside the view of the GC, including
pointers within absoluteSD that point to other chunks of memory
we pass into MakeAbsoluteSD.

CL 653856 recently allowed more make results to be stack allocated,
which worsened the problems here and made it easier for those
pointers in absoluteSD to become dangling pointers, though the
core problems here existed before.

This CL instead allocates absoluteSD as a proper SECURITY_DESCRIPTOR
struct so that the GC can be aware of its pointers. We also verify the
pointers are as we expect, and then set them explicitly
in view of the GC.

Updates golang/go#73199

1b2bd6bb49 windows: replace all StringToUTF16 calls with UTF16FromString 
`StringToUTF16` is deprecated and will panic if given an "invalid"
string (in particular, one that has a null byte in it).  The replacement
function is `UTF16FromString`, and it returns an error if there was
a problem.

This change replaces all uses of `StringToUTF16` with `UTF16FromString`.
The `service` struct now no longer stores a `string` name but rather
a `*uint16` pointer to the name.

It should not be possible to panic due to UTF16 string conversion
at this point.

8f2aa9fb48 cpu: conditionally re-enable AVX512 support on darwin/amd64 
Darwin opmask clobbering bug was fixed in kernel version 21.3.0
as released in MacOS 12.2.0. This commit resolves issue by
checking for Darwin AVX512 support via a sysctl call with the
addition of a kernel minimum version check.

The kernel version check is completed without adding new
dependencies to x/sys/cpu. A sysctl call is accomplished by
copying a minimal amount of code from x/sys/unix, to retrieve
only the needed KERN_OSRELEASE value. This code is structured
in the same manner as an existing analogous AIX/PPC64 syscall.

The resulting dotted version string value is then parsed for
numeric comparison with a dependency free function.

All code in this contribution is structured to ease removal of
the special darwin/amd64 codepaths when that OS/arch combination
is eventually no longer supported by golang.

Resolves issue: golang/go#49233, reinstates fix for issue: golang/go#43089
