Feature request: use primitives from standard library

[netizen-a]

Motivation

I believe it would be more consistent with rust to make use of the resources in std::os::windows. This includes std::os::windows::raw::HANDLE and std::os::windows::raw::SOCKET.
This would make use of the standard library with windows-rs crate easier by making use of compatibility between them.

Drawbacks

None that I can see yet.

Alternatives

A possible alternative is to take the current HANDLE in windows-rs and apply a trait to it such as std::os::windows::io::AsRawHandle to convert back to the standard library types.

Additional context

This is related to #760.

The challenge with the first approach is that Windows has many handle types whereas the standard library only defines HANDLE and SOCKET and even those it defines in a somewhat questionable way (handles aren't necessarily pointers and sockets are pointer-sized integers). I would however be open to exploring implementing the second alternative of implementing the standard library trait. Also related to #1622.

Right, std::os::windows::raw::HANDLE doesn't appear to be valid. There's a handle discussion here you might find fun to read #1643. There is also rust-lang/rust#95490.

The pointer provenance stuff was the first thing that crossed my mind as well @riverar .

Thanks for the reminder. Closing in favor of those other conversations.
