[SYCL] Fix iostream removal: undefined symbol + uninitialized streams (#22354) * Define/export reportExceptionToStream unconditionally so debug TUs link against release libsycl * Delete iostream_proxy.hpp, include <iostream> directly so ios_base::Init constructs streams (fixes MSVC crash) Fixes issues introduced by #22047
