[CS] Allow getCalleeLocator to find key path component callees

Browse Source 
In order to do this we need it to take a ConstraintLocator argument so
we can tell which component we want the callee for. To make it clear
that we're looking for a callee at the anchor, also rename the member
to getAnchormostCalleeLocator.
