edje/textblock: Added edje_textblock_style_get() api.

Summary:
Now all textblock_style functionality are wrapped under api
for easy of optimization. so going forward no one should directly
acess the styles from the File . the styles should be acesses by
the internal api's provided by edje_textblock_style.
