  [clang] fix regression printing constructor/destructor names

This makes the type printer not qualify constructor and destructor names.
These are represented as canonical types and the type printer is used,
but unlike canonical types which we normally print as fully qualified,
the expected behaviour for declaration names is for them to be unqualified.

Note that this restores the behaviour pre #147835, but that
is still broken for the constructor names of class templates,
since in that case the injected class name type is used, but
here the type printer is configured to also print the implicit
template arguments.

No release notes since this regression was never released.

Fixes #155537
