Port windows implementation from winapi to windows-rs

[Xaeroxe]

winapi hasn't been updated since November of 2021, and the ecosystem seems to be making a general shift towards the officially supported windows crate instead. This PR moves ipc-channel to windows.

Some deps are still using winapi, which makes this PR a bit silly.

XAMPPRocky/remove_dir_all#43 that will eventually allow tempfile to remove the winapi dependency. They've already removed their own direct winapi dependency.

[Xaeroxe]

This is ready to be merged now. winapi is no longer anywhere in the tree due to upstream changes.

Any chance of getting this merged @jdm? It would also be nice to upgrade mio to the 0.8 series given that there are “unmaintained” advisories against at least one of its dependencies.

☔ The latest upstream changes (presumably #315) made this pull request unmergeable. Please resolve the merge conflicts.

@Xaeroxe I just tried the tests here and two of them are hanging:

• test::router_drops_callbacks_on_cloned_sender_shutdown
• test::router_drops_callbacks_on_sender_shutdown

I've pushed a PR which further updates the windows crate to the current version, but the tests are still sticking there. Feel free to cherry-pick my changes if you want.

This was due to a subtle bug in the tests. The closure appeared to be capturing a value but in actuality was capturing nothing due to the let _ = not actually creating a binding. I'm pushing a fix. The original code worked in 2018 edition but doesn't work in 2021 edition.

Thank you for doing this work!
