backend/wayland: Add active pointer per host seat 

Every host seat with pointer capability propagates events to one of
sub-pointer depending which output window we entered.
active_pointer tracks reference to sub-pointer on enter/leave events to
avoid lookup for it on every move events.

Fixes swaywm/wlroots#1499
