bors 7e7483d26e Auto merge of #110152 - ChrisDenton:windows-sys, r=thomcc 
Start using `windows sys` for Windows FFI bindings in std

Switch to using windows-sys for FFI. In order to avoid some currently contentious issues, this uses windows-bindgen to generate a smaller set of bindings instead of using the full crate.

Unlike the windows-sys crate, the generated bindings uses `*mut c_void` for handle types instead of `isize`. This to sidestep opsem concerns about mixing pointer types and integers between languages. Note that `SOCKET` remains defined as an integer but instead of being a usize, it's changed to fit the [standard library definition](a41fc00eaf/library/std/src/os/windows/raw.rs (L12-L16)):

```rust
#[cfg(target_pointer_width = "32")]
pub type SOCKET = u32;
#[cfg(target_pointer_width = "64")]
pub type SOCKET = u64;
```

The generated bindings also customizes the `#[link]` imports. I hope to switch to using raw-dylib but I don't want to tie that too closely with the switch to windows-sys.

---

Changes outside of the bindings are, for the most part, fairly minimal (e.g. some differences in `*mut` vs. `*const` or a few types differ). One issue is that our own bindings sometimes mix in higher level types, like `BorrowedHandle`. This is pretty adhoc though.
