Fix Windows console hide path targeting the foreground window

This PR addresses [Ryubing/Issues#345](https://github.com/Ryubing/Issues/issues/345) by fixing the Windows console hide/show path so it only acts on Ryujinx’s own console window instead of whatever window happens to be focused during startup. Previously, when Show Console was disabled, the helper could race with focus changes and end up affecting another app or shell window while leaving the console visible; this change removes that foreground-window dependency and keeps the startup behavior scoped to the Ryujinx console.
