The detach function declaration in `ISC__REFCOUNT_TRACE_DECL` had an
returned an accidental implicit int. While not allowed since C99, it
became an error by default in GCC 14.
`ISC_REFCOUNT_TRACE_IMPL` and `ISC_REFCOUNT_STATIC_TRACE_IMPL` expanded
into the wrong macros, trying to declare it again with the wrong number
of parameters.
