Demangle: correct demangling for CV-qualified functions 

When demangling a CV-qualified function type with a final reference type
parameter, we would treat the reference type parameter as a r-value ref
accidentally.  This would result in the improper decoration of the
function type itself.

Resolves PR31741!
