Call UpdateButtons on mouse_movement data for ALPS device

This fixes problem with B_MOUSE_DOWN messages produced by Thinkpad
TrackPoint buttons. Those messages have 'clicks' parameter always
equal to zero. Solution was suggested by korli. Thanks!

Fixes #8978

- Generate helper events for ALPS touchpads. This is needed for tap drag and edge motion. This emulates the synaptics touchpad somehow. For example, we need more events to decide if a tap is a
simple click or becomes a tap drag. ALPS does not send these events.
- Enable ALPS.
- Force const edge motion speed. Synaptics sends events with a certain frequency ALPS don't. Even worse ALPS stops sending events durring a edge motion when you don't move your finger. Current
speed is 200 pixel/s. In theory synaptics has different event frequency modes which would result in a different edge motion speed in the previous approach. Please check if synaptics works/speed is correct. Will try to get a synaptics laptop for testing...
- fix class variable names.

- ALPS and synaptics are sharing the same code to generate mouse events now. The movement generation is calibrated on the synaptics touchpad, though.
ALPS movements are fine now, hope the synaptics is still working. Please test! There are still some leftovers form switching from a c struct to a c++
class will fix that later.
- Support ALPS devices with passthrough.
- ALPS is still disabled because tap and edge motion is not working yet. The
problem is that synaptics generates more helper events which makes this a lot
easier to implement. My plan is to emulate this events to imitate the synatics touchpad.
