hwc: fix sending worng touch position when ec is transform for hwc

- generally touch position is calculated with img object size(last child object of smart object).
- if ec is transform for hwc and screen rotation, img object is resized by transformed buffer
  and then evas calculate touch position with transformed size and e20 get worng touch position.
- for calculating touch position with surface size, e20 add map_input_obj and resize with surface
  size when ec is transformed
- but evas can't change evas_object which calculated (img obj->map_input_obj) when touch is pressed
- so ec isn't available hwc if client is needed transform and touch is pressed
