elm_layout: Implement Efl.Text

This implements support for efl_text_set() for the default
part (NULL). This also adds support for efl_text_set(efl_part())
for layouts. This should cover a LOT of widgets :)

The next step is to remove Elm.Layout.text but it's used in too
many places at the moment. @herdsman!!
