Summary:
Implement support for locked pointer cursor hints. Cursor hints can be
retrieved by the compositor either continuously by connecting to the
cursorHintChanged signal or only when needed. In the later case the
compositor must connect to the aboutToUnbound signal of the locked pointer
interface in order to fetch the last hint before the interface is unbound.
Test Plan: Autotest added.

Summary:
The pointer constraints protocol is an unstable protocol and thus
the implementation follows the semantics of unstable protocols.
The protocol allows to create a constraint on the pointer - either a
lock or a confinement on a surface. Those are not activated at once, but
when the compositor actively grants it.
During lock no further pointer motion is emitted, during confinement the
pointer is kept in a certain area.
This implements T4451.
