Update eolian_cxx tests in order to remove forbidden eolian notations.
For tests with containers that support non-pointer types,
change ptr(int) to int.
For tests with containers that only support pointer types,
change ptr(int) to string.
Remove tests for features that are no longer meaningful with eolian new
Add a FIXME note to eina::range_array when used with eina::string_view.
