Tracking issue for CommandExt::show_window

[andyolivares]

Feature gate: #![feature(windows_process_extensions_show_window)]

This is a tracking issue for #126690.

The idea is to expose STARTUPINFOW.wShowWindow in CommandExt trait to control how a new process' window is displayed on Windows OS (normal, minimized, maximized, etc.)

Public API

// std::os::windows::process

#[stable(feature = "windows_process_extensions", since = "1.16.0")]
pub trait CommandExt: Sealed {
  #[unstable(feature = "windows_process_extensions_show_window", issue = "127544")]
  fn show_window(&mut self, cmd_show: u16) -> &mut process::Command;
}

+1 for this in std. Had a use case for this managing processes on a desktop OS and this was a infinitely cleaner option compared to rolling my own, correct, CreateProcessW code just to set a single flag.

I've been using this myself in a production app with no issues since the feature was merged to master. I don't think a simple flag can cause much trouble :)

Can @dtolnay help us on stabilizing this feature? Thanks!
