efl/evas/text: Fix rendering issue with changed texts of same size 

Introduce a new function called evas_object_content_change(). It should
be used when object contents get changed.

The rendering issue involving text objects was due to its map surfaces
not being freed. Thus, evas_object_content_change() is now called in
evas_object_text_text_set() during the relayout of the text for making
sure to get their map surfaces freed before rendering them.
