PS/2 interface: sense multifinger taps on FingerHigh (#21427)
Previously multifinger taps were sensed on the Z value > 0: this isn't
very correct. Accorging to the specification, Z values below 30
correspond only to a very light taps or just floating fingers. I had
run into the situation when I was clicking on the physical left button
and that click was transformed to the right button click via
ClickFinger2, but I wasn't tapping the touchpad at all. Investigations
showed very small values of Z -- my other fingers were just floating
above touchpad.
This change also makes click (and finger) detection more consistent,
because it uses FingerHigh to detect taps everywhere.
