Add support for handling generic types in LLVM backend

- Updated `lb_type_internal` to return a pointer type for unspecialized generics.
- Modified `write_type_to_canonical_string` to handle specialized generics without panicking.
- Enhanced `default_type` to return the default type of specialized generics when applicable.
