fix: use documented synch APIs

[rzhao271]

Downstream PR: zeromq/libzmq#4680

This PR would help Microsoft repositories indirectly consuming and rebuilding wepoll, such as microsoft/zeromq-prebuilt, to get into compliance with internal policies by using APIs only documented on learn.microsoft.com.

However, this PR also brings in a dependency on synchronization.lib. I'm also unsure whether there's a test suite I could run these changes against. So far, I have run the libzmq tests with these changes and confirmed they passed.

A couple of remarks:

• To my best knowledge, WaitOnAddress is allowed to spuriously wake up, which the existing code base does expect and this PR does not anticipate.
• Wepoll supports versions of windows that go pretty far back (Windows 7) and a bunch of non-msvc toolchains (e.g. MinGW). Does this PR change that?
• Wepoll relies broadly on undocumented APIs, including interaction with the AFD driver. Should I expect patches for those too?

PS: this PR was made against the "dist" branch which contains the amalgamated source code. The un-amalgamated source code, including tests, can be found here: https://github.com/piscisaureus/wepoll/tree/master

Thanks for the quick review!

The WaitOnAddress docs mention that the minimum supported client version for WaitOnAddress is Windows 8. WakeByAddressSingle has the same requirement.

As for the undocumented APIs, this PR addresses all of the in-scope ones, though I'd like to try out my changes on the master branch later this week.

Closing this PR and re-opening one for the master branch.
