touchpad: allow disabling palm detection altogether
Also a long-requested configuration option but it's difficult to expose
- depending on the touchpad we utilize different palm detection methods
and in theory may add to those at any time as we see fit.
Disabling it completely via a configuration option is only going to get
us more bug reports because *some* palm detection is likely desired on
most setups. So let's allow disabling it in a plugin and thus leave any
further palm detection code up to the plugin.
