If the touchpad is in TOUCHPAD_OFF mode, allow physical clicks

Enabling clicks in off mode also allows for the new Lenovo *40 series to use
the top software buttons while the touchpad is disabled. This benefits those
that usually disable touchpads altogether but still need the buttons for the
trackstick.

This changes existing behaviour, but TouchpadOff was always intended to stop
erroneous events while typing. Physical button presses are hard to trigger
accidentally. On the touchpads that TouchpadOff concept was originally
designed for the buttons are nowhere near the keyboard and are physically
separated from the touchpad anyway. On Clickpads, triggering a physical
click requires more force than accidentally touching the surface.

When the touchpad is switched off, button events caused by a physical
button press are still interpreted. On a ClickPad, this includes
software-emulated middle and right buttons as defined by
the SoftButtonAreas setting.
