[PATCH synaptics] Don't release the button on TS_3 if TapAndDrag is disabled (#31854)

[Peter Hutterer]

TS_3 is second tap down. Unconditionally set the button as down, later, in
HandleTapProcessing we have the required conditions to reset it to TS_START
and TBS_BUTTON_UP.

Meanwhile, TBS_BUTTON_DOWN stays down, so the second tap is counted and sent
as button event. This restores double-tapping if TapAndDrag is disabled.
