Warning! This patch is mostly file addition & deletion so not very much interesting.
Minimum changes are done since there will be another commit for kcm_touchpadx cleaning. The kcm_touchpad is changed as kcm_touchpadx and it is moved to new folder "touchpadx". Since "touchpad" folder is changed, you can review the diff by checking it. Tested on X and everything is working fine. In Wayland, the KCM is not shown at all.
