edje/optimization: keep a readonly flag on edje_style.

Authored by smohanty on Aug 11 2019, 8:16 PM.



Just to check if the edje style has text_class tag we do
lot of pointer hopping by linearly scan through the tags in the
style which is not very cache efficient.

by keeping a readonly flag we can avoid those acess if the style dosen't
have any text_class tags. and if we have those tags then we can start
updating the style straight away.

and it doesn't have any memory overhead on _Edje_Style object as it has at least 3 unused byte (padding on 32bit system)

To avoid starting ballooning the size of this structure, could you switch both Eina_Bool to Eina_Bool : 1? I know it won't impact the current style structure size, but it will give a better trend for the future.
