ecore-wayland: add Ecore_Wayland_Selection typedevs/thiep/dnd

We have copy & paste and drag & drop selection types, but we cannot
distinguish between these two types when requesters receive data
from data ready event.
This patch adds a new enum to help selection requesters distinguish
between two selection types and have suitable actions for each type.
