[PowerToys Run] Add "ignore hotkeys in fullscreen" setting (#3262) (#3604)

Connect Wox's existing "ignore hotkeys in fullscreen mode" setting to PowerLauncher and the PowerToys settings UI.

This allows PowerLauncher to ignore hotkeys if any application is currently in fullscreen mode, whether it's real exclusive fullscreen or borderless windowed mode. This applies to things like fullscreen games, video and presentations but not maximized windows.
