Some new upcoming changes require us to use Go 1.23. However, if we switch to Go 1.23 some
new linter errors are showing up. This commit fixes most of the errors and adds an
exclusion for integer overflow errors.

* 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.

Run fuzzing tests in CI.
Use race detector when running tests.
Add missing `t.Helper()` calls.
Update test helpers in `pkg/bindfilter` to use `RtlGetNtVersionNumbers`
instead of reading registry, and skip tests if not running as admin.

* Add lint and go generate stages to CI
Add CI step to verify `go generate` was run on repo.
Add linter stage to CI along with linter config file,
`.golangci.yml`.
Will likely prefer revive over static-check.
Updated README Contributing section on linting requirements.
Added sequence ordering to make sure lint and go generate stages run
before tests and build.
This way, build and tests are not run on code that could potentially:
1. not build due to `gofmt` issues;
2. contain bugs;
3. have to be re-submitted after issues are fixed; or
4. contain outdated Win32 syscall or other auto-generated files.

* Fixed linter issues
Code changes to satisfy linters:
- Ran `gofmt -s -w` on repo.
- Broke up long lines.
- When possible, changed names with incorrect initialism formatting
- Added exceptions for exported variables.
- Added exceptions for ALL_CAPS_WITH_UNDERSCORES code.
- Switched to using `windows` or `syscall` definitions if possible;
especially if some constants were unused.
- Added `_ =` to satisfy error linter, and acknowledge that errors are
being ignored.
- Switched to using `errors.Is` and `As` in places, elsewhere added
exceptions if error value was known to be `syscall.Errno`.
- Removed bare returns.
- Prevented variables from being overshadowed in certain places
(ignoring cases of overshadowing `err`).
- Renamed variables and functions (eg, `len`, `eventMetadata.bytes`) to
prevent shadowing pre-built functions and imported pacakges.
- Removed unused method receivers.
- Added exceptions to certain unused (unexported) constants and
functions.
- Deleted unused `once` from `pkg/etw.providerMap`.
- Renamed `noop.go` files to `main_other.go` or `doc.go`, to better fit
style recommendations.
- Added exceptions for non-secure use of SHA1 and weak crypto
libraries.
- Replaced `ioutil` with `io` and `os` (and `t.TempDir` in tests).
- Added fully exhaustive checks for `switch` statements in `pkg/etw`.
- Defined constant strings for `tools/mkwinsyscall`.
- Removed unnecessary conversions.
- Made sure `context.Cancel` was called.
Additionally, added `//go:build windows" constraints on files with
unexported code, since linter will complain about unused code on
non-Windows platforms.
Added a stub `main() {}` for `mkwinsyscall` for non-Windows builds, just in
case `//go:generate` directives are added to OS-agnostic files.

* Added HV Socket tests
Added tests for core Hyper-V socket functionality, including testing
CloseRead and CloseWrite, as well as checking addresses are appropriate
and timeouts work.
Added fuzzing test to check for edge case read/write issues.
