Comparison between css::uno::WeakReference and css::uno::Reference

...causes overload resolution ambiguity in C++20, as observed with recent
Clang 10 trunk with -std=c++2a:

> sd/source/ui/framework/factories/BasicPaneFactory.cxx:327:39: error: use of overloaded operator '==' is ambiguous (with operand types 'css::uno::WeakReference<css::drawing::framework::XConfigurationController>' and 'const ::css::uno::Reference< ::css::uno::XInterface>')
>     if (mxConfigurationControllerWeak == rEventObject.Source)
>         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^  ~~~~~~~~~~~~~~~~~~~
> include/com/sun/star/uno/Reference.hxx:425:28: note: candidate function (with reversed parameter order)
> inline bool BaseReference::operator == ( const BaseReference & rRef ) const
>                            ^
> include/cppuhelper/weakref.hxx:106:19: note: candidate function
>     bool SAL_CALL operator == ( const WeakReferenceHelper & rObj ) const

An alternative would be to add overloads for combinations of
css::uno::WeakReference adn css::uno::Reference, but this was the only case of
such an ambiguity across the whole code base, such just resolve it with an
explicit .get().
