elm icon/image efl ui image - respect aspect hints at all if set

these did not even look at aspect hints when calculating sizing. that
means any attempt to set them would lead to... nothing useful. this
handles horiz/vert/both cases (as best as is possible).

@fix

This reverts previous commit and fixes it in the box layout to respect
aspect in elm boxes. note - this probably needs doing in other
containers too like table...
