lokdialog: Forward mouse events to vcl; enable mouse move

The current implementation works well - the mouse events are properly
handled by the opened dialog changing the dialog states.

However, since the uno commands (dialog IDs) are different from what is
returned by LOK_CALLBACK_DIALOG_INVALIDATE, the invalidation doesn't
instantaneously, so one have to make the dialog window out-of-focus and
then again back to focus to trigger the paint and see the updated dialog
state.

The mouse coordinates are forwarded in pixels as of now.

Enable mouse GDK Motion mask too for mouse move operation.
