Expose process windows_process_extensions_main_thread_handle on Windows

~~I did not find any tests in 7d3e03666a/library/std/src/sys/windows/process/tests.rs that actually launch processes, so I haven't added tests for this.~~ I ran the following locally, to check that it works as expected:
```rs
#![feature(windows_process_extensions_main_thread_handle)]

fn main() {
    use std::os::windows::process::{ChildExt, CommandExt};
    const CREATE_SUSPENDED: u32 = 0x00000004;

    let proc = std::process::Command::new("cmd")
        .args(["/C", "echo hello"])
        .creation_flags(CREATE_SUSPENDED)
        .spawn()
        .unwrap();

    extern "system" {
        fn ResumeThread(_: *mut std::ffi::c_void) -> u32;
    }
    unsafe {
        ResumeThread(proc.main_thread_handle());
    }

    let output = proc.wait_with_output().unwrap();
    let str_output = std::str::from_utf8(&output.stdout[..]).unwrap();
    println!("{}", str_output);
}

```

Without the feature attribute it wouldn't compile, and commenting the `ResumeThread` line makes it hang forever, showing that it works.
