Add handling for SDL_HINT_WINDOW_ACTIVATE_WHEN_RAISED and SDL_HINT_WINDOW_ACTIVATE_WHEN_SHOWN on macOS

- Cocoa_ShowWindow will order a window that is not being activated below the key window (if one exists) then set visible

- Cocoa_RaiseWindow calls -[NSWindow orderFront:] without changing the key window
