Append "pointer" to AbstractClient::{enterEvent,leaveEvent}

KWin handles several types of pointing input devices, e.g. mice,
tablets, etc.

As is, enterEvent and leaveEvent are very ambiguous. This change
prepends "pointer" to those methods to make it explicit that they handle
pointer enter/leave events.
