Effort/Encapsulate the Win32 thread affinity
The Win32 thread-affinity of the window create and managing functions is inherited by VCL from Windows. This results in code to need explicitly taking care of this, e.g. by delegating function invocations into the "main" thread.
Use a private thread for window creation and message handling. Delegate all calls leading to the invocation of these functions into the private thread. Use the extended Binary Uno threading-model to simplify the implementation.
