d3d11videosink: Fix for unhandled mouse double click events

Browse source 
Only window created with CS_DBLCLKS style can receive those mouse
double click events, so we need to use the style for internal/external
windows can get double click events.

Also, passthrough mouse events to parent window in the same message pumping
threads instead of manually forwarding each mouse event.
