convert UnoControlModel and friends to use std::mutex

Which means creating a variant of the cppuhelper::OPropertySetHelper
helper class which uses a std::mutex.
Since we can do virtual base classes now (which the original could not), use that and a new helper
class comphelper::UnoImplBase to share
std::mutex m_aMutex;
bool m_bDisposing;
fields that the OPropertySetHelper wants to share with the parent class.
