edje: Edje_Edit - add functions that allow user to set and get value of fill type

Summary:
This commit contains two new functions for setting and getting value of
fill type of IMAGE and PROXY parts: edje_edit_state_fill_type_get() and edje_edit_state_fill_type_set()
Also with this commit printing of not default value of fill type (TILE) on generation of edc code is added.
