eolian_cxx: update tests to no longer use forbidden eolian notations

Summary:
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
restrictions.

Add a FIXME note to eina::range_array when used with eina::string_view.
