Previously, we would instantiate the UDL by marking the function as referenced and potentially binding to a temporary; this skipped transforming the call when the UDL was dependent on a template parameter. Now, we defer all the work to instantiating the call expression for the UDL. This ensures that constant evaluation occurs at compile time rather than deferring until runtime. Fixes Issue 54578.
