Improve frontend handling of SYCL special types

### Is your feature request related to a problem? Please describe

The clang frontend currently requires SYCL special types to have a public default constructor in order to have a uniform way of initialization before calling the `__init` method on them.

This is a design choice that forces implementers to always add a public default constructor to special types and in doing so possibly deviating from the spec with `sycl::stream` being such an example.. This issue serves to track this long term effort to improve the frontend handling of special types to not rely on the default constructor.
