Don't disable trackpad whilst using keyboard
Currently, when any letter key on the keyboard is held, the trackpad is disabled. This makes it very difficult to play games that both require mouse and keyboard input without an external mouse. It would be great if libinput would match the behavior in Windows 10, and not disable the trackpad by default.
