Backends: Win32: fixed ImGuiMod_Super being mapped to VK_APPS instead of VK_LWIN||VK_RWIN (#7768, #4858, #2622)

Amend 075576744

The `ImGui_ImplWin32_UpdateKeyModifiers()` function maps `ImGuiMod_Super` to `VK_APPS`, the "Application" key located between the Right Windows (Super) and Right Control keys on the keyboard, see https://conemu.github.io/en/AppsKey.html

This means that when using `ImGui::GetIO().KeySuper` to try to get the down state of the `VK_RWIN` or `VK_LWIN` keys, it'll always return FALSE when either of those keys are held down, and only return TRUE when `VK_APPS` is held down.
