[elementary][atspi] change accessible description to char* from const char*

Summary:
The accessible name is char*, this could confuse API user.
If we provide user callback to get description, an user would return allocated string.
The usage of elm_interface_atspi_description_get/set should be same with elm_interface_atspi_name_get/set
