Eric Fiselier a18ef6f1f9 Fix PR31916 - std::visit rejects visitors accepting lvalue arguments
A static assertion was misfiring since it checked
is_callable<Visitor, decltype(__variant_alt<T>.value)>. However
the decltype expression doesn't capture the value category as
required. This patch applies extra braces to decltype to fix
that.
