* Update to go 1.21
Use `atomic.Bool` stdlib instead of including our own.
Include `tools\mkwinsyscall` updates from go-winio/283 to switch to
`syscallN`.
Note: removed `// TODO` about `print`/`ln`, since the latter adds spaces
between args when printing, which is undesired.
Also update CI to run steps on windows-2022 instead of windows-2019,
similar to our hcsshim CI.

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.

* Add `fs.ResolvePath` to resolve symbolic links
`filepath.EvalSymlinks` does not work well on Windows, and can enter
infinite loops in certain situations and error out.
Use Win32 API GetFinalPathNameByHandle to handle path resolution.
Implementation based off on: https://github.com/containerd/containerd/pull/5411

Update logic to try querying for normalized path initially, then use
opened path if access is denied.
