[PATCH v2 libinput 3/3] touchpad: hook up to the tapping configuration

Now that we have run-time changes of the tap.enabled state move the check
to the IDLE state only. Otherwise the tap machine may hang if tapping is
disabled while a gesture is in progress.
Two basic tests are added to check for the tap default setting - which is now
"tap disabled by default", for two reasons:
* if you don't know that tapping is a thing (or enabled by default), you get
spurious button events that make the desktop feel buggy.
* if you do know what tapping is and you want it, you usually know where to
enable it, or at least you can search for it.

Changes to v1:
- changed to simple enabled/disabled configuration
- updated tests for rebase on master
- add comments why tapping is disabled by default
