edje: Move text_change_cb to legacy only

This should probably be replaced by a well defined signal.

Note: If edje sends signals on swallow/unswallow and text set/unset we
could simplify some of the elementary code, eg. for button's icon
handling. The theme should be handling the padding automatically, it's
not the elementary widget's role
