ecore-wl2: add functions for proxying a selection receive externally 

in some cases (e.g,, x11 bridged selections) it is necessary to use
alternate means when transferring a selection, and so performing the
entire piped receive is not necessary. instead, extend the lifetime
of the data offer until the proxied receive has completed
