evas_map: added precise coord get/set APIs

Parameters of evas_map_point_coord_get/set are integer coordinates values,
so any caller of APIs can not get/set coordinates of evas map accurately.
For improving accuracy of that, below two APIs using double value are added.
 - evas_map_point_precise_coord_set
 - evas_map_point_precise_coord_get
