primary-selection: introduce wlr_primary_selection_source

Browse source 
This is a common interface that can be used for all primary selection
protocols, as discussed in [1]. A new function wlr_seat_set_primary_selection
is added to set the primary selection for all protocols.

The seat now owns again the source, and resets the selection to NULL when
destroyed.
