Update go1.21 and CI (#315)

* 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.

GUID tests to use t.Run (#256)

Switched to subtests using `t.Run()` for GUID testing, rather than using
log statements to demarcate different tests.

Added `.String` to GUID `Variant` and `Version` using
`golang.org/x/tools/cmd/stringer`.

Added `tools.go` to version `stringer` in go.mod and allow
`go generate ./...` to be run without needing a `go get` call.
Based off of [go wiki](https://github.com/golang/go/wiki/Modules#how-can-i-track-tool-dependencies-for-a-module)
recommendation.
