headline: c++/reflection: Fix error with ODR-used inline consteval variables.
tldr: The compiler now correctly handles ODR-used inline variables of consteval-only types by checking for DECL_INITIAL.

The compiler was incorrectly issuing an error for ODR-used inline variables of consteval-only types. The fix strengthens the check in wrapup_namespace_globals to also verify that !DECL_INITIAL is true before issuing the error. This ensures that variables with definitions are not erroneously flagged as missing definitions.
