Michael Stahl 78f05c0a65 toolkit: avoid deadlock in UnoControl::setDesignMode() 
Avoid deadlock by disposing the accesibility context without the Mutex
locked, since it will eventually try to acquire the SolarMutex...

Thread 1 in UnoControl::getPosSize()
calling from sdr::contact::ControlHolder::getPosSize()

Thread 2 calling from UnoControl::setDesignMode()
trying to get SolarMutex in VCLXWindow::disposing()
