Where ever possible, use golang.org/x/sys/windows instead of syscall (which has been deprecated since go1.11).

Using windows.LocalFree requires using unsafe.Pointer, which ensures that the Go garbage collector does not try to free memory pre-maturely if it was previously declared as a pointer.

Since syscall.Handle is part of API for vhd package, it was left unchanged.

For security descriptor functions, switch to using windows.SECURITY_DESCRIPTOR to avoid unnecessary byte manipulation and panics due to missing input validation and error checking.

oa.ObjectName = &ntPath
oa.Attributes = windows.OBJ_CASE_INSENSITIVE

// The security descriptor is only needed for the first pipe.
if first {
if sd != nil {
//todo: does `sdb` need to be allocated on the heap, or can go allocate it?

nope, i wasn't able to track it down in the docs or code
i figured we can dig into it in the future, when we clean up the code paths here (and move most of the code to dedicated pkg/pipe dir?)
