tdf#103852 avoid clipboard deadlock
Deallocate the XTransferable object async using AsyncCallback
(that uses Application::PostUserEvent) which executes the
callback in a thread-safe way on the main thread. This avoids
a deadlock at deallocation so that the XTransferable.
Modify AsyncCallback to not hold the SolarMutexGuard because
Application::PostUserEvent is considered thread-safe.
Document Application::PostUserEvent thread-safety
